wondering if anyone can help me with my problem. Our older dog is 2. Ive noticed in the past 3 days some weird behavior. I say just noticed b.c we do not see other dogs hardly ever. She has always been very good with other dogs, doing normal dog sniffing when another dog comes close. Lately she has lunged and nipped when the dog gets up to her. other wise if the dog is far away she could care less its only when the dog gets near her. Like I said we really do not see other dogs, and her behavior has certainly changed since we got the puppy 4 months ago. We took her on a hike on Monday, she did very good, with one dog that was on a leash, 2 other dogs not so much, she went to nip them in the face when they got up to her. we took our dogs for a walk last night and we went a different route thinking maybe our routine is to much the same, and a St Bernard jumped over a fence and charged us. ran off with the owner in tow, then when we where almost home found us again(with owner) got away from her again, and our dog , with hair raised on end, when he got close lundged and tried to nip him in the face. im not saying bite bc this nip is like the "get the hell away from me nip she does with the puppy" kinda fast and just with her front teeth. I really dont know if that is important. I just want to help her with her obvious anxiety towards dogs. The first lundge is always this nip, the second lundge I fear maybe a bite. like I said before we really dont see other dogs when we are out other than if they are in their yard barking at us. I read on another thread to give her treats. I did have some treats with me last night and she wanted nothing to do with them . They where just regular treats though, should I use something more like chicken? She is not food driven like the puppy. I wish I knew someone with a dog, but I really dont. our inlaws have a dog but they dont take him out of the house, and I really dont want to have her on his territory if she tries to bite him. He is much bigger than her, probably well over 110lbs, I think he is a retriever. other person , doesnt keep their dog on a leash. ever. There are leash laws here in Mass, I am just worried if I cant get them apart. I really dont know how to approach this and give her good dog interactions. Not sure if this is important also but when dogs walk by the house she freaks out, and it is hard to calm her down. Our puppy who is 6 m, is in training class. Should I put our older dog in training class too. (not the same one, its half over) My theory is that our puppy when we first got her constantly nipped at her feet (vet thinks shes part GS and part Border collie) , it would drive Dusty nuts. the puppy hardly does it anymore, I just think its in the back of Dustys mind. I just dont know how to help her.
