🐾 When is a dog considered old — and how can you truly support your furry friend through every stage of their life?

There comes a moment when you notice it. Not on a specific day, not through a diagnosis. It just happens. The dog gets up a little slower. Their eyes aren't quite as sharp anymore. The walk that used to seem endless now becomes a little shorter.
And you ask yourself: Is this old age already? Or is this normal? And - what can I do now?
I know these questions very well. Bakku, our beloved male dog, passed away at 14 years old. Poor eyesight, poor hearing - but he walked his paths until the very end and protected Grandma until his last breath. And Dixi, our Bernese Mountain Dog, left us far too soon. I'm not writing this to make you sad. I'm writing it because I want you to know: This article comes from real experience.
What I want to convey to you is: Old age is not a destiny one simply endures. It's a phase that can be accompanied. Accompanied well. With knowledge, attention - and a little zeolite.

❓ The most frequently asked questions at a glance (FAQ)

When is my dog considered a senior?

This depends heavily on the size and breed. Small dogs age slower than large ones. An 8-year-old Chihuahua is still in the prime of its life - a 7-year-old Irish Wolfhound is already a true senior. As a rough guide: the larger the dog, the earlier old age begins. You can find the exact table further down in the article.

My dog has trouble getting up. Is this normal aging or do I need to go to the vet?

Both answers can be true - and they are not mutually exclusive. Stiffness when getting up is one of the most common signs of osteoarthritis (joint wear, where the cartilage between the bones breaks down and movement becomes painful) in old age. This is common and treatable. Please go to the vet - not because it's dramatic, but because quality of life can be significantly improved with the right support.

Can zeolite extend the life of my old dog?

I won't promise you that - that wouldn't be honest. What I can tell you is: Zeolite can significantly improve the quality of the last years. Fewer toxins in the body, relieved liver and kidneys, better digestion, fewer silent inflammations in the body. Together, this means: your dog stays vital longer, enjoys life longer, can truly participate longer. Not a promise of longer life - but a better life, as long as he lives. That's actually the more beautiful thing.

What are the most common health problems in old dogs?

Joints and osteoarthritis, kidney and liver problems, declining eyesight and hearing, dental problems, heart problems, tumor diseases, and cognitive impairments (when the dog acts confused or disoriented - similar to dementia in humans). Not every old dog gets all of these. But knowing what's possible helps you to look closely early on.

What do whiskers have to do with age?

Whiskers - also called vibrissae or tactile hairs - are highly sensitive sensory organs. They help the dog to orient itself, estimate distances, and perceive air currents. In old age, when sight and hearing decline, these tactile hairs become even more important - essentially the last reliable antennas. For them to regrow and stay strong, the body needs silicon (a mineral essential for hair, tendons, bones, and connective tissue). Zeolite contains natural silicon and can gently support this. And please - never cut the whiskers. In Austria and Germany, by the way, this is legally forbidden.

My dog eats less in old age. What can I do?

This is very common. Several small meals instead of one large one, easily digestible food, warming the food slightly to enhance its smell, zeolite gently supports digestion. And if the dog really stops eating - please go to the vet, as pain or an internal illness could be behind it.

How do I explain it to my children when the dog dies?

This is the hardest question in this article. Despite being a psychologist. Or precisely because of it. I allow myself to say: Honesty in age-appropriate language is best. Children sense more than we think. They also sense our grief. Telling them that the dog went to sleep without pain and won't come back - that is more loving than hiding it. And being allowed to grieve together is a gift, not a mistake. My niece drew a beautiful picture of a rainbow bridge for Bakku - actually Grandma.

When is a dog actually old?

This is not as easy to answer as one might think. Because 'old' is not a number - it's a condition. Didn't Oprah say: Age is just a number. And this condition depends very much on size, breed, nutrition, and living conditions.
As a rough guide, this table applies:

Breed size	Senior from approx.
Small breeds (up to 10 kg)	from 10–11 years
Medium breeds (10–25 kg)	from 8–9 years
Large breeds (25–45 kg)	from 7–8 years
Very large breeds (over 45 kg)	from 6–7 years

Ezra, our Labrador Retriever, is 6 years old and currently feeling the full force of spring. He's far from being a senior yet. But I'm already thinking today about how I want to accompany him in a few years. Because prevention is always better than cure. And to be completely honest, I notice that when playing fetch, he takes a break after 3 throws and lies down in the sun. He never, ever would have done that before.
Bakku was 14. A very old age for a medium-sized dog - and he bore it with dignity almost to the end. Poor eyesight, poor hearing, but he knew exactly who was where. And he protected Grandma. Until his last breath.

Old Dog – What Really Changes in the Body

We once went on holiday to South Tyrol in a dog hotel. Next to us, an old female dog was lying on her blanket - she had such difficulty getting up. And her owner said, very simply, very lovingly: She was always with us everywhere. So she is now too. Everything just takes longer.
That sentence never left me. Because it says everything you need to know about accompanying an old dog. It's not about speed. It's about being present.

What really changes in an older dog's body:

The Joints

Arthritis (joint wear, where the protective cartilage between the bones breaks down) is very common in older dogs. It can be recognized by difficulty getting up, stiffness after lying down, and reluctance to climb stairs. The dog acts as if everything is fine - dogs show pain very little. That's precisely why we need to pay attention.
What helps: A soft bed, gentle regular exercise (short walks, no forcing), silicon for cartilage and connective tissue, zeolite for detoxification that can fuel joint inflammation.

Liver and Kidneys

In old age, the liver and kidneys - the two main detoxification organs - work slower. Toxins, metabolic products, and drug residues are no longer broken down as efficiently. Zeolite binds exactly these substances in the intestine before they burden the liver. This is particularly valuable in old age.
Lilly's owner wrote to us (Lilly is the female dog in this title picture)

"Lilly is already having a harder time getting up. Zeolite detoxifies and removes metabolic waste products from the body. Moving is then easier. We are already happy about that."
— K.G. — Labrador bitch Lilly ⭐⭐⭐⭐⭐

Coat, Skin, and Whiskers

With increasing age, the body's silicon reserves decrease - and this is noticeable. The coat becomes duller, regrows slower, and the skin becomes less elastic. And the whiskers - the vibrissae (highly sensitive tactile hairs that help the dog orient itself, estimate distances, and perceive even the slightest air currents) - need silicon to remain strong and functional.
This is particularly important because sight and hearing decline with age. The whiskers then become the dog's most important antennas. They are essentially the second eyes - and they must never be cut. In Austria and Germany, this is legally prohibited, and for good reason.
Zeolite contains natural silicon and thus gently supports from within - coat, skin, connective tissue, bones. Not as a quick fix, but as a daily companion.

Digestion

The intestine becomes sluggish with age. The intestinal flora changes, nutrient absorption decreases, constipation or loose stools occur more frequently. Zeolite regulates the pH value in the intestine, stabilizes the intestinal flora, and calms digestion. Sigrid from Munich wrote to us:

"Our older female dog (12) now gets it added to her dog food, and after 2 days, I see how her stool stabilizes. I will feed the zeolite daily. It is visibly doing her good. The fact that it is completely natural is super good."
— Sigrid from Munich ⭐⭐⭐⭐⭐

Sight and Hearing

At the end of his life, Bakku saw poorly and heard little. And yet he knew exactly who was there, who was coming, who needed protection. Towards the end, he even barked at us. When he perceived us. Dogs compensate for declining senses astonishingly well - through smell, through their whiskers, through the deep familiarity with their humans. What helps: maintaining routines. The old dog needs predictability more than ever. Always the same voice, always the same place, always the same food.

Cognition — when the dog seems confused

Some old dogs develop cognitive dysfunction (a type of canine dementia — the dog appears confused, disoriented, sleeps a lot during the day and is restless at night, sometimes doesn't recognize familiar people). This is not common, but it does exist. If you notice this — please go to the vet, there are ways to help.

Why zeolite is so valuable for old dogs
I said earlier: zeolite does not prolong life. What it does — and that is no less — is to relieve the body. And a relieved body stays vital longer. Specifically, for old dogs, this means:

• Liver and kidneys have fewer toxins to break down — because zeolite binds and excretes them in the intestine
• Ammonia (a metabolic waste product that is less efficiently broken down in old age and can burden the brain) is bound
• Silent chronic inflammations in the body are reduced — less inflammation means less joint pain
• Silicon in zeolite supports coat, whiskers, bones, and connective tissue
• Digestion becomes calmer and more stable

Maria and Helmut wrote to us about their old Entlebucher Mountain Dog — and their report deeply touched me:

"Our old male dog was sluggish, listless, simply not himself anymore. We thought it was just old age. Since we started giving him zeolite, he is much livelier and seems generally relieved. I wish we had tried this sooner."
— Maria and Helmut S. — Entlebucher Mountain Dog ⭐⭐⭐⭐⭐

'I wish we had tried this sooner.' I hear that often. And that's why I'm writing this article. So you know it sooner. Especially because it's so easy and simple to incorporate into the daily routine.

About Sammy, Bella, Bakku — and the grandpa who, after two weeks, still brought a female dog home

Tina wrote to us about Sammy — her 15-year-old Galgo from Spain, rescued from a life that wasn't beautiful, and then lived so long and well. In the middle, by the way, is Rommi - she was Ezra's first girlfriend and taught him how to dart. Learning how to zig-zag from a female Galgo teacher is just perfect. There's little better.

"On the left you see Sammy. He's already 15. I support him with zeolite for detoxification, and his gut is also well-regulated by it. Rommi and Filou also get it in their food. For dog tummy well-being."
— Tina — Galgos Sammy, Rommi and Filou ⭐⭐⭐⭐⭐

And Claudia wrote to us about Bella, her 13-year-old Cocker Spaniel:

"Bella got old, and every change in food was a risk. When she started leaving her food, I was desperate. Zeolite was my last attempt - gentle, natural, without side effects. She eats again, has a shiny coat, and looks at me with those bright eyes. I know I did the right thing."
— Claudia — Cocker Spaniel Bella, 13 years old ⭐⭐⭐⭐⭐

Bakku, Entlebucher Mountain Dog with food optimized with zeolite, very irregularly, whenever we remembered. And in old age, we noticed a difference when he got zeolite. Then he was much livelier.

And then there was Bakku. Our Bakku. 14 years old, poor eyesight, poor hearing - but he left when he was ready, in his own way, with dignity. At some point, he no longer felt like getting up. After that, Grandma absolutely didn't want another dog. Too much pain. Too much farewell.

Grandpa disagreed. After two weeks, he appeared with a female dog from the "divorce orphanage" — already 8 years old, a little grey around the muzzle and with difficulties shedding, with a history. And Grandma's heart, which had actually closed up — it reopened in no time. Because that's what dogs do.
This isn't a zeolite issue. This is a life issue. But I'm telling it because it shows: The heart recovers. Again and again. And the next dog deserves the same care, the same attention, the same knowledge. And please, no comparisons. Everyone is unique with their individual characteristics and also their ability to commit.

Zeolite for older dogs – why detoxification is so important in old age

Not every product suits every situation. Here's an overview:

DOGKRAFT Zeolite — the daily basis
Daily with food, from the first signs of age, preferably even before. Detoxifies, stabilizes the intestines and digestion, relieves the liver and kidneys, supplies silicon for fur and connective tissue. This is the core of daily support.

DOGKRAFT dosage for seniors:

• Daily: 0.5% of food quantity — mix well into food
• Under stress (after medication, illness): up to 1% of food quantity
• Always offer fresh water — especially important in old age
• Examples:
  Dog 10 kg, eats 350 g daily → 1.75 g DOGKRAFT daily
  Dog 25 kg, eats 650 g daily → 3.25 g DOGKRAFT daily
  Dog 35 kg, eats 800 g daily → 4 g DOGKRAFT daily

TIERKRAFT Zeolite skin powder — for skin and wounds

Older dogs often mean: thinner skin, slower wound healing, irritated areas. TIERKRAFT skin powder with organic lavender oil can be sprinkled directly onto irritated or sore spots — soothing, anti-inflammatory, drying for weeping areas. Our customer wrote to us:

“Our dog was bitten 5 times by another dog. We gently applied the ointment everywhere and applied TIERKRAFT skin powder to the deep bite wounds."
— Customer ⭐⭐⭐⭐⭐

STEINKRAFT wound ointment — for wounds that want to heal

If the skin is already drier, spots are healing, scars are forming — the wound ointment with 5 µm fine zeolite clinoptilolite supports regeneration and keeps the skin supple. Especially for older dogs who recover slower than before. And whose wound healing is simply slower.

AM+PLUS Active Microorganisms — for gut and coat

Apply freshly mixed (small amount of AM+PLUS with water, use immediately — microorganisms lose their potency with prolonged air exposure) to fur and skin. Strengthens the skin microbiome (the natural balance of beneficial bacteria on the skin), reduces odor, cares for irritated fur. Internally as daily support for the intestinal flora — particularly valuable after medication or illness.

A brief digression: The whiskers — why they are worth gold in old age

I want to explain this in a little more detail, because hardly anyone knows — and because I find it so fascinating.

Your dog's whiskers — also called vibrissae or tactile hairs — are not normal hairs. They are highly sensitive sensory organs. Each individual whisker sits in a special hair follicle (hair root) which is surrounded by a network of nerve endings. The slightest touch, air currents, changes in the environment — the dog perceives all of this through its whiskers.
They are located above the eyes, on the muzzle, on the chin — wherever the dog gets close to things it cannot see directly. They are virtually second eyes for the near range.

In old age, when sight and hearing decline, these tactile hairs become even more important. They are often the last reliable sensory organ that helps the old dog orient itself. Bakku saw little and heard little in the end — but he knew exactly who was there. I believe his whiskers helped with that. For whiskers to grow back well and maintain their function, the body needs silicon. This mineral is the building material for hair, tendons, bones and connective tissue — and it decreases with age. Zeolite contains natural silicon and can provide gentle daily support here.

Important: Never cut whiskers! Cutting the vibrissae is legally forbidden in Austria (§7 Animal Welfare Act) and Germany (§6 Animal Protection Act). It is the temporary amputation of a sensory organ. Especially in old dogs with declining sight and hearing, the absence of whiskers can lead to serious disorientation. Please explicitly point this out to your dog groomer.

Diet for older dogs – what seniors really need

An old dog's stomach is more sensitive, kidneys tolerate less protein, the liver needs relief. What this means in practice:

• High-quality, easily digestible protein — lean meat, steamed fish, no cheap fillers
• Low fat — relieves liver and pancreas
• Many small meals instead of one large one — the old digestive tract will thank you
• Omega-3 fatty acids (salmon oil, hemp oil) — anti-inflammatory, good for joints and fur
• Fresh water at all times — kidneys need fluid especially in old age
• DOGKRAFT Zeolite daily — detoxifies, stabilizes, supports from within

One more practical tip: Slightly warm food for old dogs. The smell becomes stronger, the dog eats better. Sounds trivial. But it works.

When to definitely see a vet?

I say this again and again because it's important: Zeolite and natural support are complementary — not a substitute for veterinary diagnosis. In old age, this is even more true.

🐾 Please have these signs checked promptly: Severe stiffness or pain when getting up and moving Sudden weight loss without reason Greatly increased or greatly decreased thirst Confusion, disorientation, wandering around at night Coughing, shortness of breath or unusual fatigue Lumps or hardening under the skin Sudden loss of appetite for more than 2 days

And please: Annual blood tests from senior age onwards. Liver, kidneys, thyroid — many things can be treated well if found early. This is not a luxury. This is care.

Dippel, Odor & Minni – understanding small signs of aging

Bakku had small lumps under his skin in old age — we lovingly called them Dippel. While petting, you suddenly find them, get a brief fright, and wonder what they are. In most cases, these are lipomas (benign fatty tumors — soft, movable, painless, a purely age-related phenomenon that occurs very frequently in older dogs, especially in Labrador Retrievers, by the way — Ezra, I'm looking at you). They usually don't require treatment but should be checked by a vet once and regularly monitored — so you know what is changing and what is staying the same.

And then there's the smell. Older dogs sometimes smell more intensely "doggy." This sounds trivial, but it's completely normal — the skin produces more sebum (natural skin oil), the gut flora changes, metabolic products are no longer excreted as efficiently. Zeolite binds precisely these odor-forming substances already in the gut — it's no coincidence that "the smell has improved" is one of the most common phrases in our customer reviews.

Winnie/Minni doesn't like to walk a single meter - but she loves playing fetch. You can't imagine how much. And being completely competitive and performance-oriented, she wants to be the faster one to snatch the ball. Because she doesn't do anything during the week and catches up on everything on weekends when the Viennese are there, she gets incredibly sore muscles.

Oh yes — and then there's Minni. Her real name is Winnie, Grandma and Grandpa's new dog. But Grandma and Grandpa couldn't relate to the name (they don't know Winnie the Pooh) and now call her Minni. She doesn't mind at all. The main thing is to have a mommy and daddy again. She is 8 years old, comes from the "divorce orphanage" — that's what we call homes for dogs that were given up because their humans separated — and she doesn't like to go for long walks anymore. Neither do Grandma and Grandpa. Perfect match. The fact that she sometimes eats things not meant for her — yesterday, for example, half the cake Grandma baked for the priest — that's another story. If you couldn't always be sure where your next meal was coming from earlier in life, you grab it when the opportunity arises. You can't blame her. 🐾

Aging Quirks – why old dogs suddenly have their own ideas

Old dogs develop quirks. This is not imagination or a training problem — it's age. And somehow also character.
Bakku, for example, in the end had his very clear ideas about which path was the right one. Not the fastest. Not the shortest. His way. And if you tried to redirect him — well. He ignored it.

Typical aging quirks that many dog people know:

Routine is sacred. Always the same walking route. Always the same time. Always the same sleeping spot. Woe betide Grandma if she rearranges the furniture. This isn't stubbornness, by the way — it's security. An old dog who can't see or hear well relies on what he knows. Changes confuse him. So please: leave the furniture alone.

Sniffing now takes longer. Three minutes at a blade of grass. Five minutes at a lamppost. The old dog is reading the newspaper — he just takes a little longer. Let him. It's his walk, not yours.

Affection. Some old dogs suddenly become more affectionate than before. They want to know where their human is. Always. This sounds exhausting — but it's actually the biggest compliment a dog can give. Or it's the other way around: Rico, our neighbor's old male dog, can't hear anything anymore. But that's not what I wanted to tell you now. He leaves the room when his mom and dad come and goes to the other. Rico wants peace and quiet. And the whole room to himself.

No desire for other dogs anymore. The old dog has fulfilled his social obligations. He doesn't have to play with everyone anymore. He's allowed to be selective. We're allowed that in old age too.

And then there's Minni. She doesn't like to go for long walks anymore. Neither do Grandma and Grandpa. If it fits, it fits. 🐾
And another quirk that you should know — because it can sometimes be startling: the old dog who suddenly growls. Bakku sometimes growled in old age when the children touched him too roughly. That wasn't aggression. That was communication. An old dog who is in pain, who hears and sees less well, who gets scared when someone suddenly pulls him — he will eventually say: Please don't. And growling is his "please don't."

Important: Never punish growling. A dog who is no longer allowed to growl will eventually bite without warning. Growling is a gift — it's the last friendly warning. Accept it. And explain it to the children too. An old dog deserves respect. 🐾

P.S. I took a closer look at the story of the Rainbow Bridge — and discovered something that truly touched me. Actually, it's not "he crossed the Rainbow Bridge." Because in the original poem — written in 1959 by a 19-year-old Scottish woman named Edna Clyne-Rekhy after her Labrador Major died — the animal waits before the bridge. In a sunny meadow, without pain, without illness. And it only crosses over when its human comes. Together.

"He is waiting at the Rainbow Bridge" would therefore be the correct expression. And somehow, also the more beautiful one. He isn't gone. He is waiting.

You can find the complete original poem on rainbowsbridge.com 🌈🧡

Okay, Ezra has nudged me three times already for a game of fetch. He wants to go out again. His master is away in Tyrol, Marika already took him for a walk (a long one) at lunchtime, and now it's my turn.
