I was wondering if anyone might have any tips on this. Heidi seems to have some agression to other dogs. She really is a sweet and loving dog, and when she lived at the shelter, I was told she got along well with other dogs. However, anytime we are out for walkies and one or more of the neighbor's dogs are outside, we have to go the other way. I am so afraid of her biting another dog! Before I moved here, there were a couple other dogs in my old apt building...my next door neighbors got a boxer pup and she couldn't stand that dog...I had gotten into the habit of taking her leash off as soon as we walked into the building and she would run up the stairs and wait for me to open the door. One day, the neighbor was coming out w/ Izzie and he barely got into his house fast enough. Heidi did nip Izzie, but not very hard and the neighbor was really good about it. This year, my sister is bringing both of her dogs up for Christmas, and I have some concerns about it. Her Buddy generally reacts to dogs the same way Heidi does, but given some time to work it out, he ends up being ok. I refuse to board her over Christmas, and we can separate all the dogs if need be, but what can we do to help them get along? Buddy E hated my Buddy until my sister accidently let mine onto the porch where her's was playing. Buddy E had my Buddy pinned down by the throat, barking and growling in his ear. He never bit him and within a few minutes decided Buddy was ok and from then on they pretty much got along. My concern with doing something like that w/ Heidi is that Buddy E is handicapped and has a very bad lower back. Heidi is considerably bigger than him and I am so afraid of her hurting him. I just don't want ot have to bannish Heidi to the basement the entire weekend!!! I already told my sister that we will have to rotate dogs in the basement as it simply isn't fair to leave mine down there the whole time, and she agreed. I am really hoping that they can all get along but I am afraid to even bring Heidi near Buddy E or Mac for that matter. I also feel bad about this because I won't be able to take Heidi to any meet ups, as I would feel awful if she bit another dog...not to mention the liability. I want so badly for her to be able to get along with others!! I am afraid of taking her to a class for fear she'll bite. Any suggestions??
