I have 22 years of experience training recused dogs. Everything from food aggression to potty training. I am expert in this field and work part time as a private trainer for rescued dogs. This will include fear biters as I have a specialty in working with them. I have many references available and i as well run a 501c3 Great Dane rescue. My experience in training is vast in both large and small breed animals. I may not have all the answers but i will find out if i don't know. Please consider using my services.
