My senior dog is suddenly aggressive, biting, and having accidents. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 11 years and 8 months old | 70 lbs

My dog is 11 year old pit bull. She has suddenly started to bite family members and growl and bark at them too. When we correct her she growls at us and refuse to listen. She also was pooping and peeing in the house it has stopped but still happens once in awhile. She has also been chewing on her paw so bad it bleeds and she llimps. She refuses bath time as well. We don't know what to do, I'm worried because I have a newborn and I'm scared what she will do. Any advice??

The sudden temperament change can be due to stress from a new baby or maybe an indication of pain or a neurological problem such as tumor or dementia. You can talk with your vet about medicine for pain but with a new baby it is probably safest to not chance it and always keep them separate. If the medicines do not help and her behavior continues then I am afraid your only other option is considering euthanasia for everyone’s safety. I am so sorry you are faced with this!
