I have a 8 month old rottweiler puppy. From day one she has not liked to be held or cuddled. She gets along great with our other dog, but they do get a little agressive towards each other. Well today they got a little snarly and i was in between them. They lunged at each other and my arm was in the middle. I ended up in the ER for a dog bite. Puncture wounds! My husband was so furious that he said we were taking her back to the breeder. I am upset because I feel like I have givin up on her. I would like to try obedience training. I can't have an agressive dog. Any help or suggestions appreciated!!!
