As I've stated before, Jackson doesn't really like strangers. He's fine when we're not at home, unless someone acts scared, but at home it's horrible. The problem is that my sister, who lives with us, has a new boyfriend that visits regularly. At first I was fine with putting Jackson in the crate when he came over, but now he's coming over nearly every night. When Jackson's out, there is a lot of barking, which is unusual for him. I think most of the barking is just territorial. Another problem is that this boyfriend is a know it all... he thinks that because Jackson's tail is wagging, that he must just be excited. I've known that dogs can bite with their tails wagging... I know that this wagging is more of an uncomfortable wag. Should I make Jackson stay in a down postion the entire time this boyfriend is here? Is there anything else we can do to make these visits more comfortable for everyone?
