Hello,
I adopted a shih from a rescue about 8 months ago. I fell in love with him when I saw him playing with a tennis ball happily at the shelter. No one informed me that he was aggressive and a biter until after I had already adopted him and he bit me the first day I had him! The rescue stated they hadn't seen this behavior because they simply had let him run in the shelter and he was basically just left to be part of the group.
He growls when you tell him no,Or try to discipline, He Then begins to escalate and bite incessantly until I Try to put him on his side and show him who's in charge. It's a fight. I try to remain calm. It has gotten worse since we left from out of town for about ten days then another week last month.
I do allow him to sleep on the bed and sit on furniture which I know has to stop. My husband thinks it's time to return him. Just this morning when my husband got back into bed at 3 am he started growling and biting and it took an hour for him to calm down. He then went and peed in the hallway. We have struggled with this for months. My husband wants to return him. I cannot bear thought of giving up on him. My other two non aggressive dogs run and hide when he acts out.
I am at my wits end. I do not want to give him up but this unstable behavior is unacceptable. Any suggestions would be greatly appreciated.
