Is it ethical for vegans to keep pets?

The objection

“You say it’s wrong to use animals, but you keep a dog or a cat and control its whole life for your own enjoyment. Isn’t that exploitation too? You’re being inconsistent.”

The answer

The Vegan Society defines veganism as seeking to exclude “all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose” [1], and sharing a home with an animal need involve neither. Whether it does turns on whose interests come first: a pig bred and fattened for slaughter serves the people who eat it at its own expense, while a rescued dog that is fed, walked, taken to the vet and put before its guardian’s convenience is the one being served. Meat eaters draw their own line when they love dogs and eat pigs; vegans draw it by what the relationship does to the animal rather than by species.

Is it wrong for a vegan to keep a pet?

Keeping a pet fits veganism when the animal already needs a home and its welfare comes first, in the way that looking after a child or a frail relative counts as care even though it governs much of their life. The law in England and Wales lists what that care involves: under the Animal Welfare Act 2006, whoever is responsible for an animal must take reasonable steps to meet its needs for a suitable environment and diet, to behave normally, to be housed with or apart from other animals, and to be protected from pain, suffering, injury and disease [2]. The same duty covers a farmed pig, but it is weighed against “any lawful purpose for which the animal is kept” and does not apply to killing an animal humanely [2], which is what the pig is kept for. What a vegan should put in a cat’s bowl is a harder question than whether to keep one.

What is wrong with breeding pets to sell?

Breeding animals to sell is where the objection has force, because the animal is made to suit the buyer and bears the cost when that goes wrong. In a 2024 analysis of 584,734 dogs in the UK, flat-faced purebreds had a median lifespan of 11.2 years against 12.8 for medium-faced ones, and French Bulldogs 9.8 years, though purebreds as a whole lived slightly longer than crossbreeds [3]. Among 2,781 French Bulldogs under UK veterinary care in 2016, the odds of 20 of 43 common disorders were higher than in other dogs, and the odds of brachycephalic obstructive airway syndrome, a breathing disorder, about 31 times higher; the authors tied many of these to the extreme body shape that defines the breed (O’Neill and colleagues, 2021) [4].

How a puppy is sold matters too: those sold before six weeks of age, or without the buyer seeing the mother, tended to have more health disorders at 21 months old, their owners reported, in a UK survey of 985 puppies bought in 2020 (Dale and colleagues, 2026) [5], and since April 2020 England has banned anyone but the breeder from selling puppies and kittens under six months old [6].

Meanwhile the animals already born need homes. In 2025, US shelters and rescues took in 5.8 million dogs and cats from their communities, adopted out 4.2 million, returned 638,000 to their owners and euthanised 597,000, according to Shelter Animals Count, a data programme of the animal charity ASPCA [7][8]. Taking in an animal that is already in a shelter pays no one to breed another, which is the reasoning behind “adopt, don’t shop”. That holds only where the rescue isn’t buying from breeders itself, and some rescues are: in 2018 the Washington Post found that bidders linked to 86 rescue groups, advocacy groups and shelters had spent $2.68 million on 5,761 dogs and puppies at two government-regulated dog auctions in Missouri since 2009 [9].

Should pets exist at all?

Animal-rights thinkers disagree about whether domesticated animals should be phased out, though Gary Francione, who wants domestication to end, says the animals alive now need care. The Rutgers University professor wrote in 2012 that breeding animals to keep as pets cannot be justified, yet “they are here now and they need our care”; he urged readers to adopt or foster, and wrote that he and his partner lived with five rescued dogs [10]. Will Kymlicka, co-author of the book Zoopolis with Sue Donaldson, argues instead that domesticated animals “should be recognized as full members and co-citizens of society”, which he called “a promising way of ensuring justice without having to seek their extinction” (2014) [11].
