We have a 4 month old puppy that displays uncontrollable aggression to other dogs. We socialize him at pet stores, horse shows and with kids at every opportunity. I'm concerned because he's going to outweigh me when he's mature and he has already lunged at my friends dog and his teeth nicked me in the thigh when I got in the way.

Hi Cindy,

We have a 4 month old Caucasian Shepherd puppy and he displays uncontrollable dog aggression to unfamiliar dogs. I have read that this breed of dog is very independent and does not have the best recall. Having owned a protection trained Malinois and a German Sheperd, I am amazed at how intense this puppy can be.

He lives with an 8 year old male German Shepard and a 10 year old female border collie. They all get along although his "puppy play" can be rough. We socialize him at horse shows, pet stores, and with children with every possible opportunity.

My concern is when he is a 150 - 180 pounds and outweighs me and my teenage children. He got into with my friend's Puggle (the Puggle lunged at him) and I happened to be in the crossfire and got teeth-nicked on my thigh.

We have been committed from the beginning on working him knowing that consistency and training is key for his proper development; however, I realize an average dog trainer will not cut it.?Do you have any recommendations for dog trainers specializing in protection/large dogs in our area?

Thank you for guiding us in a good direction.
