My dog became aggressive and nips after spaying. What's wrong?

How long ago was it when she was spayed? If it was very recent, is she on pain meds? If not then I would recommend discussing this with your veterinarian and see if they can put her on some type of pain medication. If it wasn't within the last week then it most likely has nothing to do with pain related to the spay and there may be something more going on which would require a vet visit and potentially a trainer.

Thanks for using Petco Pet Education Center, formerly Petcoach! Spaying can certainly correct aggressive behaviors or tendencies so that is something that can certainly help in Luna's case. If that is not corrected after surgery or you prefer not to spay her, I would highly suggest a qualified dog trainer or behaviorist that can help you with this in person. While correcting these types of behaviors is possible, it usually requires in person training. Good luck and have a great day!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. No, this isn't normal behavior after spaying, and spaying doesn't cause aggression. It could be Clementine saw something at the vet that upset her, and she redirected her aggression at your other dog when she got home. I'd keep an eye on her for now, and if this behavior continues, I'd take her back into the vet. Best of luck.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If this is a sudden behavioral change I would have her examined. She could be painful or not feel well and she is acting out because of that. It is better for her health to be spayed, she is at risk for an infected uterus which is an expensive surgical emergency. Hormones can affect temperament, so it MAY help but it might not be the solution. If her exam and blood work are normal, you can have her spayed then consider training and medications to control her aggression. I hope this helps and I wish you and Bella the very best!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Mylah and her apparent aggression. Aggression problems can be very complicated and complex. One thing you should do initially is take her to your veterinarian and let them make sure that she is healthy and that nothing appears wrong medically. Pain, etc can bring about aggression and irritability problems. Once the medical check is cleared, then you can discuss with your vet exactly what is going on behaviorally. Your veterinarian may want to refer you to a certified trainer or animal behaviorist to try to sort out what is triggering the aggression. I see she is spayed so we can rule out irritability/aggression associated with her heat cycles. I wish you the best of luck with little cutie Mylah.

Unfortunately, this is a really common change in 2 year old dogs. Molly is reaching social maturity and things that used to bother her slightly but not cause a reaction are causing BIG reactions. She was probably always a bit nervous around other dogs, and now she's showing it. I recommend backing off her interaction with other dogs, so she's not practicing this aggressive behavior. No dog parks, etc. Then ask your veterinarian for a referral to a good trainer who can work with you on counter conditioning and desensitization to help Molly learn that other dogs aren't scary. This book is also very helpful if you don't have access to a trainer: https://www.amazon.com/Feisty-Fido-Help-Leash-Reactive-Dog/dp/1891767070

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. I would contact a behavioral trainer first. This situation must be so hard for you, and you need to get them into training as soon as possible to deal with it. I hope this helps!
