Hi, my parents have a Shih Tzu, now 5 years old, and spoiled to the core. He bites/growls, is very stubborn, leads when you walk, and generally thinks he is the boss. He can be a very loving dog, he just hasn't been taught right. My brother and I are trying to correct his behavior when we visit the house but the parents simply refuse to treat him like a dog instead of a person, so he ignores it as soon as we leave. They're getting frustrated and often very arrogantly entertain the idea of giving him away or some such thing. My question is, having lived with my parents for 5 years, would he be able to handle having a new house and new owners (my brother and I)? Also, I know separation anxiety is a problem with the breed, so would leaving him with friends or neighbors be a good idea while at work? Provided they don't break the training. Being at home alone is an option but work days can be extremely long sometimes. I would like to give him a better home, so any help is greatly appreciated.
