In search of a dog trainer, for a 2yr old male, lab mix. We have had him since he was 8wks old, and he has grown up around dogs of all sizes, and been around different people on a regular basis. He has always been high anxiety, but it has been getting worse. We have tried prescribed medications from the vet, but it did not help. He has started to show some aggression, and we really want to curb these behaviors. Please pm me if you have worked with dogs like this, or know someone who does. Thanks...
