My dog is suddenly aggressive and biting. Should I put her down?

Updated On September 23rd, 2025

My friends dog has been aggressive lately, which is out of character. She got into a fight with the neighbors dog and in a fight with the other household dog and ended up biting her father in law when he tried to break it up. She doesn't know what to do and is considering putting her down. She is a 1 year old pit bull and may be pregnant.

I'm sorry to hear that your friend is having this problem! Serious aggression issues like this can be treatable in some cases, but these situations are very complicated and need to be handled by a professional in person. I would recommend having your friend get in touch with a veterinary behaviorist to set up a consultation if she wants to try and keep the dog - the behaviorist can evaluate the dog in person to help determine the best treatment plan for the aggression, which may include medication as well as management and training. You can search for a board-certified veterinary behaviorist in your area here: www.dacvb.org
