Lexi was spayed on dec. 14th and I've noticed a personality change in her. I was wondering if anyone else noticed something similar in their babies. We took her back to the vet to have the morphine patch removed and when the vet tech came out to get her my sweet, loving puppy turned into Cujo

! I had to put her one the floor and let the young lady drag her into the examination room where she finally turned docile enough to be handled. Now when a new face comes to our house she snarls and barks for a long time. I guess I knew she would get cautious at some age but it was so sudden. Now she desperately needs to go to the vets to be groomed but I'm afraid she'll have a vicious reaction to the groomer. Anyone else have this happen

?
