How to Care for a Senior Dog: Vet Checks, Diet, Mobility and Comfort at Home

Caring for a senior dog comes down to more frequent vet checks, a diet and exercise routine adjusted to your dog’s age, and a home set up for comfort and easier movement. AAHA recommends that senior dogs see a veterinarian at least twice a year, usually with blood and urine tests, because health can change quickly in older animals. Watch closely for changes in appetite, thirst, weight, mobility, sleep and behavior, and report them early.

This guide covers general care only. Your veterinarian is the right person to assess any change in your dog’s health.

When is a dog a senior?

There is no single age. AAHA’s canine life stage guidelines define a senior dog as one in roughly the last quarter of its expected lifespan. Because large and giant breeds generally have shorter lifespans than small breeds, a Great Dane may be a senior years earlier than a Chihuahua. Your vet can tell you when your dog has reached this stage.

Common changes in older dogs

• Slower movement and stiffness, especially after rest or in cold weather
• Graying fur around the muzzle and eyes
• Weight change: gain from lower activity, or loss that may signal illness
• Cloudy eyes or reduced vision and hearing
• Dental problems, bad breath or difficulty chewing
• More sleep and less interest in long walks
• Behavior changes such as confusion, night waking or new anxiety

Some of these are a normal part of aging. Others can be signs of pain or disease that can be treated, so do not assume a change is just old age without asking your vet.

Vet care for senior dogs

Twice-yearly visits give your vet the chance to catch problems early. At a senior visit, your vet may:

• do a full physical exam, including weight and body condition;
• recommend blood work, urinalysis and sometimes blood pressure checks;
• examine teeth and gums and discuss dental care;
• check joints, muscles and how your dog moves;
• review medications, supplements and diet;
• update vaccinations and parasite prevention as needed.

Before each visit, write down anything you have noticed: changes in drinking, urination, appetite, sleep, behavior, coughing or lumps. Short videos of unusual behavior at home can also help.

Diet and weight

• Keep your dog lean. Extra weight puts more strain on aging joints. Our guide on how to tell if your pet is overweight explains body condition scoring.
• Ask your vet before switching to a senior food. Older dogs’ needs vary, and some medical conditions call for a prescription diet that only your vet should recommend.
• Choose a complete and balanced food that meets AAFCO nutrient profiles for your dog’s life stage, and change foods gradually.
• Watch appetite and water intake. A sudden increase or decrease is worth a call to your vet.
• Do not add supplements on your own. Discuss joint supplements or anything else with your vet first, since some interact with medications.

Exercise and mobility

Older dogs still need daily movement to keep muscles strong and joints working, but sessions should usually be shorter, slower and more frequent. See our guide to how much exercise a dog needs for more on adjusting by age.

• Choose soft, even surfaces where possible.
• Let your dog set the pace and turn back if it lags.
• Avoid exercise in hot or very cold weather.
• Gentle mental work, like sniffing games and food puzzles, keeps older minds active without strain.

Making your home easier for an older dog

1. Add traction. Rugs or runners on slippery floors help dogs with weak back legs.
2. Use ramps or steps for cars, sofas or beds, or block access if jumping is risky.
3. Provide a supportive bed in a warm, draft-free spot. Thicker, orthopedic-style beds can be easier on joints.
4. Raise bowls slightly if bending seems uncomfortable, unless your vet advises otherwise.
5. Keep routines predictable, especially for dogs with poor vision or hearing. Avoid rearranging furniture.
6. Offer more frequent potty breaks, including one late at night.
7. Groom gently and often, checking for lumps, sores and overgrown nails, which older, less active dogs wear down less. Our guide to trimming dog nails can help.

Cognitive changes

Some older dogs develop cognitive dysfunction, sometimes compared to dementia. VCA Animal Hospitals describes common signs, including disorientation, changes in how a dog interacts with family, sleep-wake changes, house soiling, changes in activity and increased anxiety. Pain, vision or hearing loss and other illnesses can cause similar signs, so a vet exam is important. Read more in VCA’s guide to senior pet cognitive dysfunction.

When to call the vet right away

Contact your veterinarian or an emergency clinic promptly if your senior dog:

• collapses, has a seizure or cannot stand;
• has trouble breathing, a persistent cough or pale gums;
• has a swollen or hard belly, retches without producing anything, or seems restless and in pain;
• stops eating or drinking, or vomits repeatedly;
• is drinking or urinating much more than usual;
• loses weight without explanation or develops a new or fast-growing lump;
• suddenly becomes disoriented or seems in pain.

Quality of life

As dogs age, many owners worry about knowing when a dog is no longer comfortable. Keep track of good days and bad days, appetite, mobility and whether your dog still enjoys favorite things. Your veterinarian can help you assess quality of life, discuss pain management, and talk through options when the time comes.

Bottom line

Senior dogs do best with twice-yearly vet visits, a healthy weight, gentle daily activity and a home adapted to their changing bodies. Report changes early instead of putting them down to age, and work with your vet on diet, pain and comfort.

FAQ

At what age is a dog considered senior?

It depends on size and breed. AAHA defines a senior as a dog in roughly the last 25% of its expected lifespan, which comes earlier for large breeds.

Should I switch my older dog to senior food?

Possibly, but ask your vet first. The right food depends on your dog’s weight, health and any conditions such as kidney or dental disease.

How often should an older dog see the vet?

AAHA recommends at least twice a year for senior dogs, with routine blood and urine testing as your vet advises.

Is it normal for an older dog to sleep more?

Yes, some increase is normal. But sudden changes in sleep, restlessness at night or confusion should be checked by your vet.
