This article is part of my FAQs series.
For well over a decade, I have been answering anonymously submitted questions on my Tumblr blog. Over that time, I have noticed many recurring themes, concerns, and misunderstandings.
This series brings together concise, practical responses to the questions I am asked most often, based on real conversations with people at every stage of thinking about veganism.
If you’d like to see more entries in this series, you can find them here.

The Short Answer
Yes. If you care about animal welfare, adoption is almost always the more ethical choice.
Millions of healthy animals are abandoned and killed every year because there are not enough homes for them. Buying from breeders adds more animals to an already overwhelmed system. Even so-called “responsible” breeders contribute to this problem.
If your goal is to give an animal a good life, and ensure that other animals don’t suffer in their place, adopting from a shelter or rescue is the most consistent way to do that.
The Detail
Why This Question Matters
Shelters in many countries are overcrowded. Millions of animals are abandoned, surrendered, or born into unstable situations every year. Many of them are euthanised simply because there is nowhere for them to go.
Against this backdrop, deliberately creating more animals for sale is difficult to justify.
The Scale of the Overpopulation Problem
In the United States alone, millions of companion animals enter shelters every year, and millions are killed because they are not adopted. Similar patterns exist worldwide, though many countries do not even record comprehensive figures. These numbers do not include animals who die:
- On roads
- From starvation or dehydration
- From untreated illness
- From exposure
- Through informal culling
This means that the true scale of suffering is even greater than official statistics suggest. When shelters are already overwhelmed, adding more animals to the population worsens an existing crisis.
Why “Responsible Breeding” Is a Misleading Idea
Many people defend buying from breeders by appealing to “responsible breeding.” They argue that careful selection and screening of buyers makes breeding ethical. In practice, this argument is mostly based on wishful thinking.
No breeder can guarantee that an animal will never be abandoned, surrendered, or rehomed. Life circumstances change – people lose jobs, move house, develop illnesses, have children, or lose interest.
Even in the best-case scenario, where a breeder takes animals back, a purchase has still replaced an adoption. For every animal bought, another animal remains in a shelter. That animal is therefore more likely to be euthanised. This is true regardless of how well-meaning or responsible the breeder may be.
Why “No-Kill Shelters” Are Not a Solution
“No-kill” shelters are often presented as proof that overpopulation is no longer a serious problem. Unfortunately, this is misleading, since most no-kill shelters:
- Rely heavily on donations
- Have limited capacity
- Can only accept a small fraction of animals in need
Keeping an animal alive for years requires food, medical care, staff, space, and infrastructure. This is extremely expensive, and very few shelters receive adequate public funding.
Without euthanasia elsewhere in the system, shelter populations would grow beyond what organisations could sustain. This is not a defence of killing animals, it is a recognition of how severe the crisis already is. The real solution is reducing breeding, not pretending that the problem does not exist.
“But I Want to Know Their History”
Some people buy from breeders because they believe that a breeder can give them better information about health and behaviour. In reality, this is often overstated.
While genetics matter, an animal’s environment, socialisation, training, and treatment usually have a much greater influence on behaviour. A calm, healthy parent does not guarantee calm, healthy offspring.
Shelter and rescue workers, on the other hand, usually spend weeks or months observing an animal. They can often provide detailed, honest information about temperament, needs, and medical history. Shelter staff have no financial incentive to mislead you. Breeders do.
The Desire for Specific Breeds
For most people, the main reason for buying from breeders is wanting a particular breed. In most cases, this is about preference, appearance, or status, not necessity.
With rare exceptions for specialised working roles, there is usually no practical need for a specific breed. Breed-specific rescues exist for almost every popular breed. People who want a certain type of dog or cat can usually adopt one, it may just take more time and effort than buying from a breeder.
Choosing to buy instead of adopt is therefore rarely about necessity. It is about personal preference. From an ethical perspective, preference is not a strong justification for contributing to overpopulation.
Adoption and the Ethics of Care
When you adopt, you are not creating demand for more animals. You are responding to an existing injustice. You are providing:
- Safety
- Stability
- Medical care
- Companionship
- A permanent home
This is harm reduction in practice. It does not undo the damage humans have caused, but it helps one individual animal escape it.
Asking the Right Question
Before acquiring an animal, it is worth asking yourself: “Why do I want to do this?”
If the answer is: “I want to help an animal who needs a home,” then adoption is the natural choice. If the answer is: “I want a particular look, breed, or image,” then it is worth reflecting on whether that desire justifies contributing to a harmful system.
Animals are not fashion items, accessories, or lifestyle statements. They are individuals with their own interests, desires and preferences.
A Matter of Responsibility
Humans created the crisis of pet overpopulation and euthanasia through:
- Commercial breeding
- Irresponsible ownership
- Abandonment
- Lack of regulation
- Treating animals as commodities
Because we created it, we have a responsibility to address it. That responsibility begins with prioritising animals who already exist, rather than creating more.
