Hi,
We have a beautiful 3 year old working cocker spaniel. We also have a 20 month old and a 4 month old. When we go to my parents house (they have an elderly dog who she has known since she was a pup) our dog will sit on the sofa and when their dog comes into the room she starts becoming agressive snarling, growling and barking. She also does it at our house if a dog walks into the room. This seems to have started once the new baby came along. I am not sure if she is guarding the room or if she’s guarding the children. Sometimes she won’t do it but sometimes she will. There seems to be no pattern. She goes to doggy daycare and gets on with the dogs at our house otherwise, just seems to be when she’s sat on the sofa and a dog walks in. Sometimes we think it’s overtiredness. We have absolutely no idea how to fix this or even if there’s a way. We had a dog behaviourist help us years ago with her general house behaviour but cannot afford to get another one at the moment. Needless to say we are being extremely careful with her around the children and is quite a worry. Any advice would be much appreciated.
