We have a young (10 week) lab pup. I have a feeling that he will be "hard-mouthed". I have introduced him to a grouse wing, and he will chomp down on it quite hard and not release. He will also "chomp" on the wing as he brings it back. Most of the time I have to pry his mouth open to get it out. He is a great retriever already, so I want to nip the hard mouth in the but, if possible. My last lab was very soft-mouthed from the start, so I never had to deal with it. He is also teething, so I know he will want to chew, but the behaviors he exhibits with the wing are chomping, not chewing in a teething sense.
He also like to "shake" the things he chews on...
Any help or references will be greatly appreciated.
