I started training my Australian cattle dog "Rose" with Felix to address some dog aggression issues. She's great when it comes to people but I've had significant issues when it comes to having her around other dogs. It had gotten to the point where I didn't take her on walks or out in public because she would try and attack any other dogs we came across. I noticed a dramatic improvement after only a couple of sessions with Felix. Today I was able to take her to group class with several other dogs without her displaying any aggression whatsoever. I am extremely happy that I can now safely take her in public and actually enjoy the experience. I am very thankful for the training she has received and would highly recommend Felix and Proving Ground Kennels to anyone looking for an excellent dog training experience.
