Aggression toward cat
I have a 5 year old, 60lb Lab/Pit mix. We found in the street in front of our house, too young to be taken away from his mother. He has skin irritation and severe anxiety issues and is currently on Fluoxetine 30mg a day. He has always been a loving dog and loves children, adults and other dogs, until recently...We adopted a kitten about a year ago, 7 months ago he attacked her unprovoked when she was walking across the floor. Cut her belly so bad it needed stitches. Since then we have also noticed increased aggression toward other dogs. When my daughter came to visit with her lab mix puppy, he snapped and fought with her on a couple of occasions, when we went to a friends house with him, he was baring his teeth at their dog, we quickly separated them and put him in his own space. Yesterday, he attacked our cat unprovoked again, she was walking on my wife's leg on the couch and he reached up and grabbed her by the head. Small cut below and small cut above her eye. I'm afraid of him doing this again and seriously hurting her or killing her. He has always been the most loving dog, likes you or children to lay on him and hang all over him. I am concerned that he might try to snap at one of our grandchildren. Could he be jealous of the cat getting so much attention that he may have been getting? Can he be trusted or do we need to consider rehoming him?
