If your dog is a purebred there are breed specific websites you can check out. If not a purebred but you know the mix most groups will welcome you as a new member. For example, one of our dogs was a German Shepherd/Collie mix so I joined a German Shepherd site. You can also post and ask questions in this thread since there are other cat members who are also experienced dog owners and knowledgeable about canine behaviors, etc. Best of luck with your new pup!
