Hi there, I am a proud new owner of a Doberman puppy and I want to make sure that my furry friend is always happy and content. While I can tell that he is excited when we play together and he wags his tail a lot, I am still not sure if I am reading his body language correctly. Can someone help me out and tell me what are some signs that Dobermans exhibit when they are happy? I want to make sure that my pup is always feeling loved and cared for. Thank you in advance for your help!
