I also suggest the Dog Whisperer. But your dog sound more submissive than dominant. I think I would try introducing him to other submissive dogs, one at a time.
Also when the dogs are interacting, you need to let them do what dogs do, and not interfere, unless of course one would be aggressive. but the sniffing and the rolling over is all part of dog language.
If you give him affection when he is behaving fearful, it will only reinforce that behavior, so it's important that you remain in a calm confident state and not act anxious or nervous or protective. Because he is taking his cue from you. |
