My dog Oliver is difficult and not welcoming to strangers or larger dogs. Since we adopted him he's tried attacking anything he's scared of. I was not even able to bring him to the grommer and we had to start trimming him ourselves. I tried training at Pet Smart and it was not helpful at all. We needed to start socializing him and correcting his behavior. I was so worried about finding a daycare that would accept him. Jeff knew how to handle him, make him submissive, and correct his behavior. He was like a dog whisperer. He took all our worries away. Oliver doesn't attack any other dogs at the daycare and spends the day playing. Oliver is improving. We have been so impressed over the last year that we are going to start private training sessions with Jeff.
