Hello all, new to this forum and wanted some input or ideas/opinions about my dog. He is a 2 1/2 year old white shepherd who constantly runs circles around my house and chews at himself. All day long he is pacing and running around the house and it's driving us crazy! I don't know if he has some sort of doggie OCD or if he is just bored. If it is boredom, what do you suggest that I can do with him. I know that they say shepherds need a "job" to do but what kind of a job? As for the chewing, I just put him on a grain/gluten free food to see if maybe he is itchy from allergies. He just finished his transfer over so it might still take a couple weeks to see if that is the cause of that. Also, any suggestions on socializing him? He is quite aggressive towards other dogs and strangers and I feel as if I can't take him anywhere out of fear of what might happen and how people will preceive him as a dog and me as a owner. He is such a sweet boy to us at home and I want him to be that way with everyone. Thanks so much for reading I look forward to the suggestions I will get!
