You do not notice it in a single day. First it is the stairs he no longer takes in one leap. Then the grey that spreads from the muzzle over the eyebrows. Then the moment you call his name and he does not react, not out of stubbornness, but because he did not hear you. And then you sit on the floor next to your dog, who was a puppy only yesterday, and realise: he is old.
This is not a sad text. It is a text about how to make these years good. Because an old dog is not a broken dog. He is a dog who needs different things than before, and who gives you something in return that no puppy can give: the calm of someone who knows you completely.
When is a dog old?
It depends on size. Small breeds count as seniors from about ten years, medium ones from eight, large and giant breeds from as early as six. A Chihuahua at twelve is in his prime retirement years, a Great Dane of the same age is a rarity. More important than the number is what you see: How does he move in the morning? How quickly does he recover after a walk? How does he hold his weight?
What changes in the body
Joints
Almost every old dog has osteoarthritis, many just do not show it, because dogs bear pain quietly. Signs: stiffness after lying down, hesitation before stairs and before jumping into the car, shorter steps, licking at a joint. This is no reason for resignation, but for action: today the vet has good painkillers and joint supplements, physiotherapy really helps, and exercise stays important. Just differently: several short walks instead of one long one, swimming instead of ball throwing.
Senses
Hearing and sight decline. A dog who hears less is startled more easily when touched while asleep. Speak to him before you touch him, or step so that he feels the vibration. Hand signals that you introduce early also work when the ears no longer cooperate. If the eyes are failing: leave furniture where it is. Old dogs know the home by heart.
Mind
Yes, dogs can develop dementia. Canine cognitive dysfunction shows itself in restlessness at night, disorientation, staring into corners, forgotten house training. There are foods with special additives and medication that help. And there is structure: fixed times, fixed routes, little change. A dog with dementia is still your dog, he just needs more support.
Organs
Kidneys, heart, thyroid, liver. Much of this only shows up early in a blood test. A senior should have a check-up twice a year, with a full blood count and urine. That sounds like a lot, but kidney problems caught early can be managed for years. Ones caught late cannot.
What you should adjust
- Food. Fewer calories, more high-quality protein, joint supplements. How much weight matters is shown by the best-known long-term study on the subject: 48 Labrador Retrievers were followed over 14 years, one half fed lean and on the slim side for life. This group lived a median of 13 years, the comparison group 11.2. That is a difference of 1.8 years. The study says nothing about how much it helps to slim down a senior who is already overweight, and it covers only one breed. But it is the best reason to take weight seriously: one kilo too much on a ten-kilo dog is ten percent.
- Sleeping place. An orthopaedic bed, not on the cold floor, not where he has to get up three times a day because someone wants to get past. Old dogs sleep 16 to 18 hours. They need a place where that can happen undisturbed.
- Flooring. Laminate and tiles turn into a slide. Carpet runners on the main routes, a ramp into the car, anti-slip socks for bad days.
- Walks. Short, often, slow. He may sniff for as long as he wants. Sniffing is for an old dog what reading the newspaper is for us.
- Brain work. Search games, a snuffle mat, small tricks while lying down. A dog who thinks stays clear for longer.
What you should not do
Spare him until he no longer moves. Comfort him with treats until he is round. Punish his accidents in the home as naughtiness. Leave him alone because he only sleeps anyway. Old dogs need closeness more than ever. Not because they are helpless, but because you are their fixed point when the world gets quieter and blurrier.
The matter of saying goodbye
At some point the question comes, and many owners fear it years before it arises. One thought that helps: more good days than bad. As long as your dog eats, is happy when you come, likes being outside, even if it is only as far as the next corner, those are good days. When the bad ones outnumber them, you will know, and your vet will help you stay honest. Because the subject deserves more room than a paragraph, it is covered in detail in Saying goodbye to your dog.
Why these years can be the best
An old dog no longer has anything to prove. He does not pull on the lead any more, he does not chase bicycles, he has stopped hating the postman. He lies next to you and is simply there, and when you look at him, he looks back, with that look that says: I know you. Everything.
An old dog's face is the most rewarding one there is for photos. Grey muzzles, cloudy eyes, an ear that no longer stands properly, and in each of these lines there is a whole life. If you want to take a photo of your senior: do it now. At the window, in afternoon light, on his spot. Not for later. For now.
A grey muzzle does not need perfect light, it needs size. In a wooden frame on the wall, that look is still there when the dog one day no longer is. You see beforehand what it looks like and can have it changed for free.
