Hello. Thanks for writing in. My name is***** and I would be happy to help you. I am not set up to do phone calls but would be happy to answer any questions you do have online. If you get a request for a phone call, it is from the website and not myself. If a dog poses a direct threat to humans and cannot be trusting even being re-homed in a new environment, then many vets would absolutely consider euthanasia and a viable option. Some ethics do come into play here because if not done, the next person that Lucy does attack may be seriously injured. I will say that some vets may want to make sure that you have done all you can with socialization, and that may include getting a consult with a veterinary behaviorist (this is actually a veterinarian with a specialized degree in behavior medicine, not just a dog trainer. The problem is that there are not a lot of board certified veterinary behaviorists out, and there may not even be one near you. Please let me know if you have any other questions or concerns. Hope this helps.
My goal is to make sure that you get all your question answered and all the information you need. If you are satisfied with my answer, PLEASE RATE IT. Rating it is the only way I get credit for helping you. If you feel like it is not helpful to you, or if there is more information you need, please respond back to me before rating. Realize that our conversation is not intended to diagnose or treat a condition. There has to be a valid veterinary-client-patient relationship established with an exam, according to law. You should always follow up with your vet.
I am sorry. I thought you mentioned that she was aggressive towards people as well. If she is just aggressive to other dogs and not people, then there may be a lot of vets who wouldn't consider euthanizing her because there are other options. They may recommend keeping her at home during the day and even putting her in a confined area or kennel if you don't want her roaming free (many, many dogs have to do this and get a long just fine) or keeping her in your backyard (assuming you live in a house) during the day, assuming it is not too hot during the summer. I will say that I have never euthanized a dog for just dog aggression, just for unpredictable aggression to people, specifically family members. A veterinary behaviorist has a lot more training with these types of behavioral issues and are better equipped to handle them then a dog trainer would be. Hope this helps.
I think for most vets that may be the case, but there are more than likely some out there that would still put her down for aggression issues with other dogs. It may be worth it to try calling around to some vets in your area to see who would be willing to do that. Let me know if you have further concerns.
