Hi, I have a 10 mth working line male who has been in schutzhund training since 4 mths of age. He is doing very well and will be training with a SAR team this summer also. His ob is great on and off the field but when we are at home at a park sometimes if he sees a dog he runs after it and I cant call him back. This dosen't happen all the time but he almost ran into the street earlier this week chasing after a dog he saw running on the side walk. The here command is great on the field but not so at home. Any suggestions? Thank you very much.
