Euthanizing a dog for medical reasons has long been seen as a way to ease their suffering. But putting a dog down for a behavioral issue like aggression is a conversation fraught with big feelings, opinions, and controversy. And the argument tends to swing between "save them all" and "euthanize all risks." But it really is never this simple.
Fortunately, over the last couple of years, the topic of behavioral euthanasia has started to be more openly discussed within the training and rescue community — but there's still a long way to go.
There is quite a bit of stigma and judgment not only against dog owners who have made the hard decision to euthanize their dog due to behavior issues but also towards rescues or shelters, dog trainers, canine behavior consultants, and veterinarians involved in those cases.
The decision to euthanize a dog for aggression is never made lightly. No one wants to make the decision to put a dog down. But someone has to when it comes to certain cases where there are no other viable options. And the people who do make that decision deserve compassion and support. The alternative is to pass along that decision to others — to another family, a shelter, a different rescue — usually with the risk of putting people or animals in danger. This is called "outsourcing" euthanasia, and it's something that needs to be addressed.
In this article, I want to share with you what behavioral euthanasia is, when it's a consideration for a dog owner or caretaker, and how I approach behavioral euthanasia with my clients. Whether you are considering this choice yourself with your own dog or you work or volunteer with a rescue organization that may need to make these decisions for the dogs in its care, it shouldn't be something that you face alone.

What is Behavioral Euthanasia?
Behavioral euthanasia is humanely ending a dog's life because of severe behavioral issues, such as aggression or extreme anxiety. Humane euthanasia is done by a veterinarian.
Dogs who are put down due to behavior problems are often young and healthy, which makes this outcome so difficult for many to understand. One Australian study found that 29.7% of euthanasias for dogs aged three and under were due to undesirable behaviors. A British study found similar results in their review of euthanasia for dogs in the same age range.
While a dog may not be obviously suffering physically, they may:
- Be suffering mentally and have a low quality of life due to the management requirements for their behavior
- Present a high bite risk towards humans or other pets in the home
- Present a high bite risk towards humans or other animals outside of the home
Behavioral euthanasia should not be considered for nuisance behaviors or other dog training issues such as pulling on a leash, barking, destructive chewing, digging, etc.
In my experience working on aggression cases, it is often the human client, not myself, that brings up the question of whether they should euthanize their dog. It is rare for me to bring it up first, but if I do, I frame it in the context of what all of the options are for behavior cases:
- Do nothing
- Manage the environment to prevent the behavior
- Behavior modification (paired with management)
These five options are the only options that any dog owner has when faced with a behavior issue, whether it's simple or complex.
My goal in situations where behavioral euthanasia is or should be considered is to provide an overview of what their options are, give them a professional prognosis for their dog's specific case, and provide support for them no matter what their decision may be. I believe that it is unethical for me as a dog trainer or behavior consultant to tell them that they should put their dog down. That is not my decision to make. My job is to make sure they understand the potential risks and liabilities of living with an aggressive dog.
Putting a Dog Down for Aggressive Behavior
If your dog is exhibiting extreme or unpredictable aggressive behavior, it's important to connect with a certified canine behavior consultant and/or a board-certified veterinary behaviorist for support and guidance. These types of behavior cases require a higher skill and experience level, so I recommend looking for a higher level of certification when it comes to choosing a dog trainer. Read about the differences between dog behavior consultant certifications here.
There are many variables in a dog's behavior case that a professional will take into account. The following are just a few of the factors that affect the risk factors of keeping the dog in the home or adopting it out to a new family:
- Are there any underlying medical issues that could be contributing to the dog's aggression? Pain often plays a huge role in aggressive behavior and treatment for medical issues may reduce the risk of aggression.
- What are the age, size, and breed of the dog? This can inform the potential damage if there is a bite incident.
- What family members are present in the home? Are they at higher risk due to their age or size? Are they competent in understanding and implementing management for safety? The presence of children automatically increases risk factors for aggression cases.
- Towards whom or what is aggression directed? Familiar people or strangers? Other animals, familiar or unfamiliar?
- What risk does the dog present to the community around their home? Has the dog been declared "potentially dangerous" by their local animal control or required quarantine after a bite incident?
Putting a dog down for behavior should not be a "snap" decision. In most dog aggression cases, there is quite a lot that can be done prior to even considering behavioral euthanasia for the dog. Rehoming or putting a dog down for aggression should not be a decision made in the highly-emotional time right after an incident unless the safety risk is high and no other alternatives are available.
Behavioral euthanasia may be something to consider when the following issues arise:
- Will required management for safety severely limit the dog's quality of life?
- If the dog escaped their home or other safety management, are they an immediate risk to people or pets?
- Would rehoming the dog place the new family at risk of being bitten?
- Are the requirements for an ideal and safe home for the dog incredibly limiting? (E.g., a dog will only do well in a remote or rural home with no visitors, no other pets, only female or only male owner(s), or only owners with extensive experience in dog training and defensive handling. These "unicorn" adoptive homes are essentially non-existent.)
Often, the most informative questions to consider are: Would I want to live next door to this dog? Would I want to live with this dog myself? Would I feel safe around this dog?
Euthanasia for Other Behavioral Issues
Behavioral euthanasia is not limited to only aggression. A dog may be suffering mentally from issues like severe separation anxiety and extreme fear or may engage in self-harm behaviors that greatly affect their quality of life. In these cases, euthanasia may be considered after exploring other treatments.
What are the Alternatives to Behavioral Euthanasia for a Dog?
Strict Environmental Management
Whether on its own or combined with training and behavior modification, management of the environment is all about making everyone as safe as possible. For certain aggression issues, such as resource guarding, this may be as simple as only feeding the dog in their crate at mealtimes and making sure no one in the family approaches. Or management may require two layers of separation between pets in the home to prevent altercations, such as two hardware-mounted gates between their own areas with visual blocks.
When practicing separation between pets, it's important to think through the entry and exit protocols for people coming and going into those spaces, as well as how you would move the dogs outside for potty breaks, etc. Simply setting up a crate for one dog to be in while the other roams around the same room is not the answer. Not only does this severely affect the quality of life for the crated dog, but it also can increase tension and contribute to worsening behavior.
Management may include training a dog to wear a basket muzzle and always having them wear it when they leave the house on a leash. It may mean never taking them for regular dog walks around the neighborhood, instead providing exercise and mental enrichment at home only. It may be not ever having visitors over to your home. Management may also include incorporating prescription medications for anxiety.
But the truth is that management is never 100%. Management can and will likely fail at some point. Someone may leave a gate or door open. A gate latch may not fully close. One must always consider the "what if?" What if management did fail, and the dog got out of the yard? What if another neighborhood pet found their way into your yard unexpectedly? What if a friend or family member entered your home without you there? Could you live with the potential consequences and liability if the worst-case management failure happened?
Training for Aggressive Behavior
Many types of aggression can successfully be treated. However, true behavior change takes commitment and time, typically months or longer. And one must practice strict management while implementing a training plan to prevent rehearsal or regression.
A behavior consultant or veterinary behaviorist will walk you through the methods of behavior modification, which will likely include counter conditioning and differential reinforcement of alternative or incompatible behaviors (DRI/DRA). These focus on changing your dog's emotional response towards the person or thing that triggers their aggression and teach your dog what to do instead of aggressing. Within each of these methods are a variety of techniques and protocols depending on the type of aggression and your individual dog.
Aggression Between Dogs in a Home
Intrahousehold dog aggression — aggression between dogs who live in the same home — is often the most difficult type of aggression to treat. There are quite a few factors that affect the treatment outcome of intrahousehold dog aggression. If you have two dogs exhibiting aggression towards each other in your home, it's crucial that you connect as soon as possible with a professional. In these cases, rehoming one of the dogs may end up being the safest choice.
Finding a new home for dogs who exhibit aggression can certainly be an option depending on what triggers their aggression. For dog-directed or animal-directed aggression, it may be possible to rehome a dog to a family with no other pets. Or a dog who becomes anxious and then fearfully aggressive towards children may be happy and stable in a home with no children or visiting children.
However, finding a home for dogs that have severe bite histories or require extensive management and handling is much more difficult, and then one must consider whether it's ethical to pass the risk to another person. Keep in mind that dogs who are aggressive toward people who are rehomed still present a liability risk to shelters, rescues, or previous owners if an incident were to occur in the future.
Many no-kill shelters find that they cannot find a foster or adoptive home for dogs with these extensive behavioral needs, which results in years of staying in a shelter environment, safety risk to staff and volunteers, escalation of behavioral issues, and overall low-quality of life for the dogs themselves. The resources required to care for this one dog also mean that a shelter cannot provide for multiple, less dangerous dogs. Hence why many no- or low-kill shelters will not accept dogs with high-level bite histories.

There may be a dog sanctuary in your area that is equipped to house your dog for the remainder of their life. However, sanctuaries are few and far between, and even rarer are sanctuaries that can provide a good quality of life and safe, sanitary living conditions for the dogs in their care. Contact your local shelters and rescues to inquire about potential sanctuary locations in your area.
