We rescued Gypsy from our local pound. She is about 1 year old, GSD. She is great with people and my 3 boys, but when it comes to other dogs she barks loudly, lunges at them, hair raises up, and is oblivious to any command. Is there anything I can do? Help I feel like we cant take her anywhere. She has become accustomed to Ben our cat, but other dogs are a different story.
