Dog Aggression Problem!
I have a dog on dog aggression problem. A couple days ago I adopted a beagle/boxer mix from the SPCA. She's a female and only 10 months old. She's playful and very stranger friendly. She gets along with dogs as well. She's an all around good dog.
I also have a 12yr old female beagle. I've had this dog since she was a pup. She's an aggressive dog to strangers, but she usually warms up to other dogs. However, for some reason she won't warm up to the new puppy. When they get near each other the older dog attacks. For now, they are kept in separate rooms, but this is not something I want to continue doing. I need to figure out how to help these two female dogs get along.
