The Best Dogs and Cats for Seniors, and When an Emotional Support Animal Letter Fits
A practical guide to the best dogs and cats for seniors: ten dog breeds and four cats with what each one asks of you, studies of size, walking, falls, lifespan, adoption and costs, and where an emotional support animal letter fits.
On this page
The best dog or cat for an older adult is the one whose energy, size and lifespan match the care you can give every day for the animal's whole life. Most lists of the best dogs for seniors rank breeds, but a 2022 study of 18,385 dogs found that breed explains only 9 percent of the differences in how individual dogs behave. So this guide gives ten dog breeds and four cats with what their own breed pages say each one asks of you, then uses published studies on size, walking, falls, lifespan, adopting an adult animal and costs to help you judge the individual animal. It also explains where an emotional support animal letter fits, which is a separate question from choosing a pet.
Energy
Choose the walks and play you can give every day, in every season, including your worst week.
Size
In US clinical records, small dogs averaged 13.5 years of life expectancy at birth and giant dogs 9.5.
Lifespan
Median longevity was 12.0 years for dogs and 14.0 for cats in England, so plan for the whole span.
Housing
Pet rules, deposits and letters are a separate question, covered in our housing guide.
These ten dog breeds and four kinds of cat are worth a look for older owners, with what each one asks of you
The American Kennel Club's article for senior owners names the Havanese, Pug, Shih Tzu, Cavalier King Charles Spaniel and French Bulldog among its breeds for older owners, and it also says small dogs are not always the better choice: they "may be easier to lift and handle, but some have high energy levels." The table below adds the Bichon Frise, Maltese, Poodle, Boston Terrier and Greyhound. Every number and quoted line comes from the breed's own page on akc.org, read on October 23, 2026.
| Dog breed, adult weight and life expectancy | What AKC says about grooming and exercise, and one thing to know |
|---|---|
| Cavalier King Charles Spaniel. 13 to 18 pounds. 12 to 15 years. | The coat "requires little more than regular brushing and an occasional bath." The dog "does enjoy moderate exercise" but is "just as glad to stay on the sofa all day." To know: AKC lists mitral valve heart disease among the conditions Cavaliers are prone to, along with a neurological condition called syringomyelia. |
| Shih Tzu. 9 to 16 pounds. 10 to 18 years. | A long coat "requires daily brushing," or a groomer can give it a "puppy trim." They "require minimal exercise." To know: because of their heavy coats and short faces, AKC says Shih Tzu "do not tolerate heat well." |
| Bichon Frise. 12 to 18 pounds. 14 to 15 years. | Brush "at least two or three times a week," with a bath and a clip about monthly, and most owners use a groomer "every four to six weeks." "Daily play sessions, in addition to walks, are required." To know: AKC says Bichons may have "early tooth loss or complications from gum infection" if dental care is not a priority. |
| Pug. 14 to 18 pounds. 13 to 15 years. | The coat "needs minimal maintenance, but it does shed," with weekly brushing, and owners can keep a Pug fit with "daily opportunities for moderate exercise." To know: like all flat-faced breeds, Pugs "sometimes experience breathing problems and do poorly in sunny, hot, or humid weather." |
| Maltese. Under 7 pounds. 12 to 15 years. | The long white coat "requires daily gentle brushing and combing to the skin." Maltese "require only occasional exercise." To know: AKC says they are "prone to dental disease as they get older." |
| Poodle, toy 4 to 6 pounds or miniature 10 to 15 pounds. 10 to 18 years for both. | Unless the coat is kept in a short trim it must be brushed daily, and many owners use a professional groomer "every four to six weeks." AKC calls the coat relatively non-shedding. To know: AKC says Poodles of any size "are very active dogs who require good exercise every day to suit their high energy level." |
| French Bulldog. Under 28 pounds. 10 to 12 years. | The short coat "sheds minimally," with weekly brushing, and a "short walk or outdoor play session" each day is enough exercise. To know: like all flat-faced breeds, Frenchies "are prone to breathing problems and do poorly in hot or humid weather." |
| Havanese. 7 to 13 pounds. 14 to 16 years. | The coat "needs to be groomed daily," and many owners clip it short to cut grooming time. AKC says they have "moderate exercise needs." To know: Havanese are "not happy left alone for hours at a time." |
| Boston Terrier. 12 to 25 pounds. 11 to 13 years. | Weekly brushing, and the coat "does shed somewhat, though not a lot." The need for exercise "varies from individual to individual." To know: like all flat-faced breeds, Bostons "can experience difficulty breathing when not given adequate shelter from excessive heat or humidity." |
| Greyhound. 60 to 65 pounds for females and 65 to 70 for males. 10 to 13 years. | The coat "requires little grooming beyond regular baths and weekly rubdowns." A Greyhound is "perfectly happy to lounge around the house all day" yet needs "a regular schedule of exercise time and opportunities to (safely) run full-out." To know: at 60 to 70 pounds it is by far the heaviest dog here, and AKC says it is "susceptible to bloat and gastric torsion." |
The Cat Fanciers' Association's breed pages describe temperament, grooming and health, but they give a weight for only two of these breeds and a life expectancy for none, so those cells say so and nothing is estimated. For a cat, the lifespan figure that exists is the English study described further down.
| Cat, adult weight and life expectancy | What CFA says about grooming and activity, and one thing to know |
|---|---|
| Ragdoll. Males can "reach or exceed 20 pounds." No life expectancy on CFA's page. | Combing "at least once or twice a week" is enough. Ragdolls are "moderately active" and "appreciate play sessions but do not insist upon them." To know: CFA says one hereditary health issue, hypertrophic cardiomyopathy, "has been found in the breed," though breeders now routinely test for it. |
| British Shorthair. Males may grow "as large as 17 pounds." No life expectancy on CFA's page. | A "quick weekly combing or brushing" is usually sufficient. They are "quiet, sedate cats" that "will wait for an invitation to sit on the couch beside you rather than jumping into your lap." To know: CFA says these cats "are not fond of being carried around." |
| Persian. No weight or life expectancy on CFA's page. | Owning one "calls for a serious commitment to regular grooming." Persians are "happier simply receiving attention and affection" than chasing toys. To know: CFA says refined facial features once led to "breathing problems" and that polycystic kidney disease "shortened the lives of many Persians in the early 2000s," and that breeders have since reduced the first and are controlling the second with genetic testing. |
| Crossbred adult cat, such as a domestic shorthair. No breed page applies. | In English veterinary records, crossbred cats had a median longevity of 14.0 years against 12.5 for purebred cats (O'Neill 2015). Ask for the cat's own weight, and ask about its coat and energy when you meet it. To know: the same study found that individual purebred cat breeds "varied substantially in longevity," so a breed name does not settle lifespan. |
Breed explains only 9 percent of how individual dogs behave, so judge the animal in front of you
A 2022 study in Science surveyed the owners of 18,385 purebred and mixed-breed dogs and genotyped 2,155 of them. Its abstract reports that "breed explains just 9% of behavioral variation in individuals" and that modern breeds are "distinguished primarily by aesthetic traits." A breed label is a weak guide to a single dog's temperament, so read the tables above as a starting list and not a ranking. What you can check is the animal itself: how big it is, how much it moves, what its coat asks of you, how old it is and what its history is.
| What to weigh, and the question to ask yourself | What a published study adds |
|---|---|
| Size. Can you lift, hold and step around this animal on a bad day? | Dogs grouped by adult weight differed in life expectancy at birth, from 13.53 years for small dogs to 9.51 for giant ones (US clinical records). |
| Energy. How many walks or play sessions a day can you give in every season? | In a study of 394 dog owners aged 71 to 82, only 36 percent walked their dogs at least three times a week. |
| Grooming. Who will brush, bathe and trim this coat, and how often? | No study we read measures grooming time, so ask a groomer or veterinarian about the specific animal. |
| Lifespan. How old will you be in 12 years, and who would take the animal if you could not? | Median longevity was 12.0 years for dogs and 14.0 years for cats in England; US life expectancy at birth was 12.69 and 11.18 years. |
| Age of the animal. Do you want to see the animal's temperament before you commit? | In a six-month study of 99 shelter dogs, owner-reported behavior changed over time, and owners reported high satisfaction. |
| Costs. What will food, veterinary visits, grooming and a sitter cost over a full year? | A Swiss survey of 1,832 adults aged 55 and older found cost is an important challenge for some older pet owners. |
Nearly 87,000 fall injuries a year are associated with dogs and cats, and the rate is highest at age 75 and older
CDC analyzed emergency room records from 2001 to 2006 and published the results in its Morbidity and Mortality Weekly Report. A follow-up study of the same data found that injury rates were highest among people aged 75 and older, and that pets were a fall hazard at every age. The figures below are national estimates of injuries associated with pets. They are not a rate per pet owner, so they cannot tell you how likely any one owner is to fall.
86,629
estimated fall injuries a year were associated with cats and dogs, 29.7 per 100,000 people.
Nearly 88%
of those injuries were associated with dogs, and dogs figured in 7.5 times as many as cats.
66.4%
of cat-related falls were caused by falling or tripping over the cat, against 31.3 percent of dog-related falls.
21.2%
of dog-related falls were caused by being pushed or pulled by the dog.
Both findings point at the same thing: how the animal behaves around your feet. The authors' own prevention suggestions were awareness of the situations that lead to falls, such as walking a dog and chasing a pet, and "obedience training for dogs to minimize hazardous behaviors such as pulling and pushing." A cat that winds between your ankles on the stairs matters as much as a dog that pulls on the leash.
A dog's adult weight tracks how long it lives, from 13.5 years for small dogs to 9.5 for giant ones
Researchers built life expectancy tables from the clinical records of more than 1,000 veterinary hospitals in the United States, covering 13,292,929 dogs and 2,390,078 cats from 2013 to 2019 (Montoya 2023, with the size-group figures in the full text). Life expectancy at birth was 12.69 years for all dogs and 11.18 years for cats. For purebred dogs grouped by adult weight, it fell as size rose.
- 13.53
Small dogs
Adult weight 5.5 to under 11 kg (about 12 to 24 pounds)
- 13.36
Toy dogs
Adult weight under 5.5 kg (under about 12 pounds)
- 12.70
Medium dogs
Adult weight 11 to under 26 kg (about 24 to 57 pounds)
- 11.51
Large dogs
Adult weight 26 to under 45 kg (about 57 to 99 pounds)
- 9.51
Giant dogs
Adult weight 45 kg or more (about 99 pounds or more)
Source: Montoya et al. 2023, Frontiers in Veterinary Science, purebred dogs by adult weight. Averages across a population say nothing certain about one dog.
Two English studies of veterinary records add detail. Dogs had a median longevity of 12.0 years, crossbred dogs outlived purebred dogs by 1.2 years, and heavier dogs lived shorter lives. Cats had a median longevity of 14.0 years, and crossbred cats lived to a median of 14.0 years against 12.5 for purebred cats. The cat figures differ because the English study took the median age of cats that had died, while the US study built life expectancy at birth from a life table, so treat roughly 11 to 14 years as a range and not a promise.
The practical use of these numbers is a question about you: add the animal's likely lifespan to your age today, and name a person who would take the animal if you could not care for it. Weight matters in the data too. In the US tables, dogs at an ideal body condition score had a life expectancy at birth of 13.18 years, against 11.71 for obese dogs, an association and not proof of cause.
A study of shelter adoptions found that dogs fostered first were less likely to be returned, so ask about a trial period
An adult animal has fewer years ahead of it than a puppy or kitten, so the commitment is shorter, and you can meet its temperament before you commit. The shelter studies we read add a caution and a tip. A two-year study of dog adoptions from shelters in Queensland, Australia found that about two-thirds of returns happened in the first 14 days, that returns plateaued at just under 15 percent, and that dog size, age and time spent in foster care before adoption were all associated with the risk. "Spending time in foster care before adoption appears to be protective against readmission," its abstract says, and it names "older or larger dogs" among the higher-risk groups.
A second study followed 99 dogs adopted from five Ohio shelters and surveyed the owners at 7, 30, 90 and 180 days (Bohland 2023). Behavior changed over the six months: separation-related behaviors and attention-seeking decreased, while excitability, touch sensitivity and training difficulty increased, and owners still reported high satisfaction. The abstract notes a common view that dogs have a "honeymoon period" after adoption. The useful move is to ask the shelter or rescue about fostering first or a trial period, and to plan on the animal settling in over months and not days.
Studies link dog walking to more activity in older adults, and they cannot show that a pet causes better health
The studies below are real, they are mostly observational, and a 2026 review calls the evidence mixed. They compare people who have animals with people who do not, and the two groups can differ in many other ways. Read the table as what each abstract reports, not as a promise of what a pet will do for you.
| Study | What was studied and what its abstract reports |
|---|---|
| Feng 2026 | The Gerontologist. A review of 26 longitudinal studies from 21 countries and regions. Twenty reported a positive association between pet ownership, successful aging and lower mortality, while some found negative or no associations. The authors write that the "evidence remains mixed" and that the impact is "context-dependent." |
| Hughes 2020 | Clinical Gerontologist. A review of 70 articles on companion animals and adults aged 60 and older. In 52, companion animals positively contributed to mental or physical health. The authors say "more and better controlled research on this topic is required." |
| Stanley 2014 | Aging and Mental Health. A survey of 830 primary care patients aged 60 and older. Pet owners were 36 percent less likely to report loneliness (adjusted odds ratio 0.64, 95% confidence interval 0.41 to 0.98), and living alone without a pet was linked to the greatest odds. It was a one-time survey, so it cannot show cause. |
| Curl 2017 | The Gerontologist. Data from the US Health and Retirement Study. Dog walking was associated with lower body mass index, fewer limitations in daily activities, fewer doctor visits and more frequent moderate and vigorous exercise. "Dog ownership was not associated with better physical health or health behaviors." |
| Gretebeck 2013 | Journal of Physical Activity and Health. A mailed survey of 1,091 adults aged 65 to 95. Dog owners who walked their dogs reported nearly 50 percent more total walking than the two groups that did not walk dogs, and 48.1 percent of dog owners walked their dogs regularly. |
| Thorpe 2006 | Journal of the American Geriatrics Society. 2,533 adults aged 71 to 82. Of 394 dog owners, "only 36% walked their dogs at least three times per week," and the mobility advantage "was seen only in dog walkers." |

A Swiss survey of 1,832 adults aged 55 and older found that "financial costs of pet ownership appear to be an important challenge for some older pet owners," notably those with limited financial resources (Meier and Maurer 2022). A 2026 umbrella review reports that qualitative research on older adults described "worries for pets' health, and pets' related expenses." Prices vary by animal, region and year, so ask your veterinarian and a local groomer for quotes. The costs that come back every year are:
- Food and supplies, which grow with the animal's size.
- Routine veterinary care, such as checkups, vaccines and dental work, plus the unplanned visit.
- Grooming, which depends on the coat and on whether you can do it yourself.
- Care while you are away or in the hospital, such as a sitter or boarding.
- Housing charges, such as a pet deposit or monthly pet rent, which depend on your lease and your state. Our guide to pet deposits and emotional support animals explains what the rules say.
Pet insurance is one way to spread out a large veterinary bill, and our guide to pet insurance for emotional support animals covers how it works and what it leaves out.
An emotional support animal letter is a separate question from which pet to choose
An emotional support animal is a companion animal with no task training. A letter from a licensed professional is what a housing provider usually asks to see when a tenant asks to keep one in a home with a no-pets policy. The Fair Housing Act asks whether a person has "a physical or mental impairment which substantially limits one or more major life activities" (24 CFR 100.201), and a licensed professional who evaluates you decides whether a letter fits your situation. Choosing a pet because you like it and asking for a letter because of a disability are two different things.
The letter
Comes from a licensed professional who decides whether it fits you. See how the letter works.
Senior housing
HUD-assisted housing for older adults has its own pet rule, covered in our Section 8, public housing and assisted living guide.
A service dog
A dog trained to do tasks for a disability. See the psychiatric service dog comparison.
Travel
Airlines may treat an emotional support animal as a pet. See flying with an emotional support animal.
In a HUD-assisted project for the elderly or persons with disabilities, the regulation says an owner may not, "as a condition of tenancy or otherwise, prohibit or prevent any tenant of such housing from owning common household pets" (24 CFR 5.309), though owners can still set reasonable pet rules under 5.318. That subpart "does not apply to animals that are used to assist, support, or provide service to persons with disabilities" (5.303), so an ordinary pet and an assistance animal request are handled separately. HUD's May 22, 2026 enforcement memo also changed which animal complaints its fair housing office pursues, and our page on HUD's rules explains what changed and what did not.
No law requires an emotional support animal to be registered, certified or to wear a vest, and no federal registry exists. A card, certificate or vest does not turn a pet into a service dog. A photo ID card and certificate is something you can add if you want one. The ADA guide shows what the law gives service dogs that it does not give emotional support animals.
Other guides cover the conditions people ask about most: depression, anxiety, PTSD and veterans, ADHD and autism. The overview of which conditions an emotional support animal letter can cover puts them side by side.
