I have been following Dave on Facebook for about 4 years now. I have used some of his methods he writes about with success with my Rottie. One problem that I haven't been able to stop is dog aggression. I have spoken to Dave 2 times now over the phone and he had suggested some training techniques to use. The more I talk to him the more I feel confident for bringing my a Rottie to him to fine tune her and help her become a more confident dog.
Since this was written, we took our Rottie, Bella to Dave. Bella spent two weeks at Dave's and we can't express enough how grateful we are to Dave We now have a well behaved secure dog. We can walk her and not worry about Bella showing aggression towards people or other dogs. We have harmony among our 3 dogs now since Bella is under control. No barking at the doorbell, dogs behind us or people making noise in their backyards. We bless Dave everyday. Believe me, it was money well spent! We wouldn't hesitate sending another dog to Dave. We have an awesome dog now that all can enjoy.
