Hi there! So little background, my girlfriend and I have a 10 month old pittie mix. For the first few months, she was great! Never had any issues with other dogs really other than a couple here or there, and she was super out going! Well, the last couple months, she has seemed to change. She had gotten more aggressive towards dogs, almost like hyperfixating on them, wouldn’t listen to us at all, and going as much as lunging at the dogs. It is weird though because as soon as the dogs are out of her line of site, she is whining for them. She also seems to have some new found anxiety and is scared of so much.
We did end up getting a 1:1 trainer that specializes in fearful and reactive dogs, because honestly we didn’t want this to become a problem later down the line, and she has gotten better since starting.
My girlfriend and I were talking the other day though and realized she has signs that she is starting her cycle soon. Our vet told us to try and get as close as we can to her starting her cycle, but to not actually get it before spaying. I just set up the appointment for two weeks from now. We almost wonder if this new anxiety and aggression could be hormone related? We’ve never gone through a dog in heat, our other female dog was spayed at 4 months old before we got her. Are behavior changes typical? Could we expect them to get better after she gets spayed?
