Aggressive Jack/Rat mix
I have a 3yr old, neutered male, Jack/Rat mix. I have had him since a pup. For the last 2 years he has developed behavior problems. I dont know what caused the issues because we didnt make any life changes at the time he developed them. I have spent over $600 in training that is not working and I dont know what else to do.
He will flip out and start barking/lunging/trying to bite my husband when he enters or leaves a room. Sometimes he will run across the room and jump on the couch to try and attack. The worst times are when my husband gets off the couch and goes to the bathroom or kitchen, or comes back and tries to sit on the couch next to me. He also is bad in the mornings when my husband leaves the bedroom to use the bathroom.
But he is very cuddly with my husband other times. I have tried rewarding him when he stops, I have tried squirt bottles, loud noises, etc to break his fit. I dont know what else to try.
Any help would be appreciated.
