Why is my French Bulldog aggressive and biting after spay surgery?

A bitch spay is a big operation and it takes a dog a good while to settle from it due to the pain and anaesthesia. This could certainly have put her out of sorts. I would give her another week or so to settle and if she is no better then, it may be personality clash and would be best to speak to s behaviourist.

Arya has been through a lot this week so I would give her a little time as she will still be very sore and disorientated from the anaesthetic. She may need a stronger painkiller so you could ring your vet. If the aggression continues over another week, I would contact an animal behaviourist before it gets out of hand.

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.

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.

I'm assuming that you may be concerned that the spay caused some hormonal change that is causing her to act like this. There have actually been various reports of behavior issues after surgical procedures and the potential causes are numerous. Bella could simply be painful, or anxious due to the trauma of the procedure. Alternatively, Bella could have had a pre-existing brain condition prior to the procedure that got worse with the anesthesia, or the anesthesia could have caused a momentary lack of oxygen to the brain that caused some damage. I would be most suspicious that this is a behavior issue rather than a more serious problem within the brain. For now, I recommend giving her a little time and see if her temperament improves. It's important to not treat her any differently, or try to handle her excessively. Treat her the same as you did before the procedure and handle her on her own terms. If the behavior persists after a month, then I recommend consulting your vet for further evaluation. At this time, it does not appear to be serious, so I would not be too concerned unless she seems to be getting worse or having other health issues. I hope that helps and all is well with Bella.

I'm sorry to hear Brandy is not acting like herself after surgery. If the surgery was recent (say within a week) she may seem aggressive because she is painful. If it has been longer than a week or so, the discomfort from the surgery shouldn't be an issue anymore. If you don't think the surgical pain is the issue, think about other changes that may have recently taken place that could make Brandy feel uncomfortable like a new pet in the household or neighborhood or a lot of visitors or children in the home. We could always set up a consultation to talk more and try to figure out what is going on and a trip to the vet to make sure she is healthy is always a good idea.

I am very sorry to hear that you are experiencing these issues with Hazel and Daisy. I believe a couple of possibilities could be occurring. Though only behaviors that will be affected by spaying are those that are under the influence of female hormones, it could be possible that they are both still undergoing hormonal changes and so they need time to adjust. The hormone changes can take up to a few months to stabilator. When everything is stablized, a dog's temperament, training, and personality, are related to genetics and upbringing, not hormones, so should not be affected. Neutering does not “calm” an excitable dog, and unless a dog is overfed or underexercised, there is no reason for it gain weight or become inactive. The undesired traits which are related to hormones such as sexual behaviours, aggression, and urine marking will change over the course of a few days to a few months. It is also possible that Hazel is possibly not healing well and still experiencing some pain or discomfort. I would try gently palpating her abdomen to see if you get any flinching nor pain reactions. A check-up with the vet to confirm she is not in pain would also be a good idea. Pain can be expressed through changes in mood, which are often outwardly viewed as aggressive behaviour. I hope that is helpful information and I wish you the best of luck with Hazel and Daisy.
