So, my boyfriend brought Dozer over to my house today just to surprise me, because he had always said he would bring him, but didn't think he would, but today, he did. So, Hank and Dozer met.. Dozer was very friendly, but, he was the first dog that Hank was NOT happy with. He was very mean, actually. I never thought Hank would actually go after him if Dozer sniffed at him or wagged his tail at him, pawed at him to play with him. Hank did not want to play at all. They both were okay within a distance, but it seemed like Hank had a major problem with Dozer for some reason. Dozer is going to be 6 years old, not neutered, but Hank is neutered. Is there a reason? It's too bad they do not get along, but Hank gets along just fine with the neighbor's dog, which is a female and about a year old. Eventually Dozer was actually afraid of Hank, we had to put him in the cage so Dozer would come inside and go out in the front yard when it was time for Mike to take him home.
