What is senior pet?
Updated By PetymFacts checked against official sources on
Quick answer
A senior pet is in the later part of its expected life. For cats, vets' guidelines say senior means over 10 years. For dogs it depends on size: AVMA counts giant breeds as seniors from about 6 to 7 years and small dogs from about 8 to 11. Old age is not a disease, but seniors need closer checks.
Also called senior dog, senior cat, older pet, geriatric pet.

At what age is a dog or cat a senior?
Cats have one line; dogs age at different speeds by size, so bigger dogs reach it sooner.
| Counts as senior from about | Who says | |
|---|---|---|
| Small or toy dog (under about 9 kg), such as a Shih Tzu or Pomeranian AVMA | 8 to 11 years | AVMA |
| Medium dog (about 9 to 23 kg), such as a Beagle or many indies AVMA | 8 to 10 years | AVMA |
| Large dog (about 23 to 41 kg), such as a Labrador or German Shepherd AVMA | 8 to 9 years | AVMA |
| Giant dog (over about 41 kg), such as a Great Dane or Saint Bernard AVMA | 6 to 7 years | AVMA |
| Cat, any breed AAHA/AAFP (Journal of Feline Medicine and Surgery, 2021) | Over 10 years | AAHA/AAFP 2021 |

What changes as a pet gets older?
AAHA's 2023 senior care guidelines warn against assuming every decline is "just age". Owners often put stiffness, weight loss, drinking more, confusion at night or a change in toilet habits down to getting old, when many of these have causes a vet can treat or ease. The guidelines describe the vet team's job as maintaining quality of life, and potentially extending it, through regular assessment rather than waiting for a crisis.
For cats, the feline guidelines set a simple rhythm: a senior cat should see the vet at least every 6 months, more often with a chronic condition such as kidney disease. Ask your vet what interval suits your senior dog. Between visits, a monthly body condition check at home and a note of weight, appetite and water intake give your vet much more to work with.
Which changes in a senior pet should you report to your vet?
None of these is normal ageing to be ignored. Note when it started and tell your vet.
- Drinking or urinating more than usual, or accidents in a pet that was house-trained.
- Weight or muscle loss, especially along the spine and back legs. WSAVA Global Nutrition Committee (chart by Tufts University)
- Stiffness, trouble with stairs or jumping, or reluctance to walk.
- Confusion, pacing or barking at night, or getting stuck in corners.
- Changes in eating, bad breath or dropping food, which can point to dental pain.
- Lumps, coughing, breathing changes or tiring quickly on walks.
How can a senior pet be kept comfortable in an Indian home?
Do
- Keep older pets cool in summer: older dogs had the highest odds of heat-related illness in a large UK study. Scientific Reports (2020)study
- Use rugs or mats on slippery marble or tile floors, and a ramp or step for a favourite sofa.
- Keep medicines on a written schedule, so family and sitters give them the same way.
Don’t
- Do not change the diet or add supplements without asking your vet.
- Do not give human medicines or anything your vet has not prescribed, even for pain. PDSA
- Do not push long walks in the heat; shorter, cooler walks suit most seniors better. Scientific Reports (2020)study

Questions owners ask
At what age is a dog considered senior?
- It depends on size. AVMA counts small dogs as seniors from about 8 to 11 years, medium dogs from 8 to 10, large dogs from 8 to 9 and giant breeds from 6 to 7. AAHA does not set one age, because dogs of different sizes age at different rates.
When is a cat considered senior?
- The 2021 AAHA/AAFP feline life stage guidelines define a senior cat as one aged over 10 years. Cats from 7 to 10 are mature adults. The guidelines recommend a senior cat sees the vet at least every 6 months, and more often if it has a long-term condition.
How often should a senior pet see the vet?
- For cats over 10, the AAHA/AAFP guidelines say at least every 6 months, more often with a chronic condition. Ask your vet what suits your senior dog. Regular checks give your vet the chance to spot changes early, before they become a crisis.
Is it just old age, or should I see a vet?
- AAHA's senior care guidelines stress that old age is not a disease. Drinking more, weight loss, stiffness, confusion or toilet accidents often have causes a vet can treat or ease. Note when a change started and tell your vet rather than putting it down to age.

- Body condition scoreA body condition score (BCS) rates a pet's body fat by look and feel, usually on WSAVA's 9-point scale: 1 is emaciated, 9 is severely obese, and the ideal sits around 4 to 5. You check how easily the ribs can be felt, whether there is a waist from above, and whether the belly tucks up from the side.
- BrachycephalicBrachycephalic means short-headed: dogs and cats bred with a flat face and short muzzle, such as the Pug, Shih Tzu, French Bulldog, Bulldog and Persian cat. The squashed airway makes breathing and cooling harder, so these pets overheat more easily, a real risk in Indian summers. Several Indian airlines refuse them in the hold.
- DewclawsDewclaws are the extra toes with claws that sit a little above a dog's foot, on the inner side of the leg, most often on the front legs. Because they do not touch the ground, walking never wears them down, so they need regular trimming. Left long, a dewclaw can curl round and grow into the toe pad, which hurts.
- Double coatA double coat is two layers of fur: a soft, dense undercoat close to the skin and a longer outer coat of guard hairs. Huskies, Labradors, Golden Retrievers and Pomeranians have one. The undercoat insulates against heat as well as cold, so vets advise brushing it out regularly rather than shaving the dog in an Indian summer.
- Indie dogAn indie dog is India's native dog: the free-living type often called the Indian pariah dog, INDog or desi dog, rather than a pedigree breed. It is usually medium-sized, short-coated, prick-eared and curl-tailed, alert and territorial. Genetic research finds Indian village dogs show little European ancestry, making them one of the world's older dog populations.
- MicrochipA pet microchip is a tiny identification chip, about the size of a grain of rice, injected under the skin, usually between the shoulder blades. It holds a unique number that a scanner reads, linked to your contact details on a database. It is not a GPS tracker. Most countries you might move a pet to require an ISO-standard chip.
- Spay and neuterSpaying and neutering are surgeries that stop a pet breeding. Spaying a female removes the ovaries and usually the womb; neutering or castrating a male removes the testicles. Besides preventing litters they lower some health risks, such as womb infection in females. The right age depends on species, breed and size, so your vet decides the timing.
