If you are looking for a submissive dog, look to it’s trainer. I personally would rather have a family oriented dog at home that is a little aggressive in the field. The last thing I want is to shoot a bird and have the dog go to retrieve it and back down to another dog. I have had Brittany spaniels stand their ground against labs and bring back my bird. Instead of all dogs being trained to same commands, confusion follows. Your dog will try to hear your voice so you are better off with your own commands. If he is trained right you probably won’t get him to hunt for someone else unless you are there
