Spayed pup turning aggressive
Hi I have 2 Shar pei's. The male is just over a year old and the female 8 months. I took het in last Saturday to be spayed. Ever since she has returned home from the vet she has been very aggressive toward the male dog. She snaps at him and bites him, she won't allow him near me or food or anything. She watches him and even chases him out of the house. He is so scared and confused at the moment he won't even come inside when I call him. They used to be the best of friends and never fought over food, attention etc. Is this happening because she is just not feeling well or in pain from the operation? Will her behaviour normalise after a few days?

Hi Amy
There may be a few explanations for this behaviour. The most likely is that your female doesn't smell the same as before and that she, as you say isn't quite recovered from the anaesthetic yet. Shar Peis are fighting dogs and are often quite aggressive towards each other and other dogs, so genes also play a part. If your bitch was in season when she was spayed, the hormones and pheromones that she produced would not have worn off and would affect her and the male's behaviour. Perhaps try separating them for a few days, but giving each one lots of attention. Take them for walks together on leads and gradually allow them to be together when you get back from walks for a little while, ignoring them completley. If they show any signs of aggression calmly separate them until the next walk. Things should normalise after a while, but if they don't then contact an accredited animal behaviourist.
