Senior dogs and chewing

Age does not remove the need to chew

Chewing is not a puppy game that dogs grow out of. It is a core behaviour, like sniffing or digging, and it does not fade with age.

In an older dog it becomes more useful, not less. Walks get shorter, running games stop, encounters with other dogs grow rare. The day empties out, and that emptiness fills with sleep, then with restlessness.

Many dogs over ten develop cognitive decline: evening pacing, aimless whining, disrupted sleep. A chewing session in the late afternoon gives that part of the day a shape, better than a stroke or a treat, because it lasts and it demands concentration.

Withholding chews from an old dog out of caution therefore trades one risk for another. The right answer is not to stop, it is to adapt.

What changes in the mouth after eight

Four changes stack up, and none of them is visible without looking closely.

Enamel wears down. The canines and molars of a twelve-year-old are shorter, flatter, sometimes browned at the tip. A worn tooth resists sideways pressure less well than a new one.

Micro-cracks accumulate. A tooth may have carried an invisible fissure for years, picked up on a stone or a wire fence. It holds. Then one day, on a hard material, it gives way — and the chew of the day gets the blame, when all it did was reveal.

Periodontal disease advances. It already affects the majority of dogs over three; by ten it is often well established. A tooth whose bone support has receded becomes a lever: the chewing force no longer applies to an anchored tooth, but to one that moves.

Teeth are missing. After an extraction, the dog shifts all the work to the other side of the mouth. He keeps chewing, apparently normally, loading the remaining teeth twice as hard.

Redo the thumbnail test, and set the bar higher

The rule holds at any age: if you cannot mark the surface with your thumbnail, it is probably too hard for your dog's teeth.

With a senior, simply apply it more strictly. What was fine at three is not necessarily fine at eleven on the same jaw — because it is no longer the same jaw.

A second test, more telling still, comes afterwards. Let your dog work for ten minutes, then take the chew back and look at it. If it shows scratches, grooves, a rasped surface, the exchange is going the right way: the chew is the one wearing down. If it is untouched, the tooth absorbed everything.

Whole deer antler already sits at the limit of that rule for a healthy adult. For most older dogs it falls on the wrong side of it.

One dental check a year after eight is worth more than any home test. It catches the cracks and loose teeth you will never see.

Arthritis changes how a dog chews, not just how he walks

A dog chews lying down, chest on the floor, both front paws pinning the chew. Holding that position means keeping the elbows and shoulders flexed for twenty minutes.

With arthritis it becomes painful. The dog settles, works for two minutes, gets up, lies down differently, then gives up. The obvious conclusion is that he does not like the chew. It is not the chew that hurts, it is the position.

Three adjustments usually fix it: a thick mat or a firm cushion instead of tiles, a flat stable piece rather than one that rolls away and has to be chased, and two shorter sessions in the day rather than one long one.

You can also hold the chew yourself for the first few minutes. Plenty of old dogs get going again once that holding work is taken off them.

What still works, and what no longer does

Coffee wood is the first choice. It is the softest of our hard woods: it crumbles into fine particles under the tooth instead of presenting a solid block, and that is exactly the profile a worn set of teeth needs.

Yak cheese comes next. It softens gradually with saliva, which makes it the most forgiving material in the range. Its milky smell also wakes up dogs whose sense of smell is fading — and appetite usually declines before chewing ability does.

Split deer antler stays possible if the teeth have been checked and the dog is not a crusher. With the marrow exposed from the start, he does not have to attack the hardest part to reach the flavour.

Whole deer antler should be set aside by default. Keep it only for a senior whose teeth have been examined, and who chews by patient rasping rather than brute pressure — that dog exists, but he is the exception.

One safety point age does not change: do not drop a size because your dog is old. A chew that is too small gets swallowed or wedged between the molars. Size follows body weight, exactly as it did at three.

The signs that mean stop

A fractured tooth hurts, but a dog almost never shows it. He goes on eating, asking, wagging. It is the details that give it away.

Watch for: chewing always on the same side; picking the chew up, dropping it, coming back, dropping it again; drooling more than usual, or saliva tinged pink; breath that turns bad suddenly; rubbing a cheek along the floor or the sofa; refusing a chew he was asking for last week.

A sudden refusal is a signal, not a mood. In an old dog it points to pain far more often than to boredom.

In any of those cases, take the chew away and book an appointment. A fractured tooth does not heal on its own, and the infection that follows eventually reaches the bone.
