OK, so I have a Mutt. We have heard that he it could be in a lab, golden retriever, pitbull, great Dane, and plenty of other breeds. He has always been relatively anxious of other dogs, he usually just whimpers when he walks past one. We lost our other dog who was a cocker spaniel about two months ago and since the he has always been relatively anxious of other dogs, he usually just whimpers when he walks past one. We lost our other dog who was a cocker spaniel about two months ago and. Lately, I have been noticing that he is more aggressive around dogs then just anxious. Especially if the past couple of days, he has been barking and even almost trying to bite other dogs while on walks. I really want him to not be scared of other dogs so that I can bring him on the walks and hiking and into town. I was just wondering if anyone else has dealt with this or if anyone has advice on how I can help him?
