I'm training my male for his master hunter tests,and he's doing pretty well. Doing some nice long triple marks and blinds. water and land. I'm thinking he's just about there when he destroys the bird on a long land mark. He does fine in his next two weeks of training then he rips up another bird on a water blind. Then yesterday another one on a water mark. He doesn't have a hard mouth, if anything he's just the opposite doesn't hold birds or bumpers firmly enough as far as I can see. I normally train with thawed birds that I collect from bird hunting and I clean them of any blood residue before they get used. I know they are not as good as fresh ones, but it's got me scratching my head as this is a new one on me. He's not trying to eat them or anything like that and I really don't notice him mouthing the birds on his way back. I have noticed some side to side head shaking but nothing real crazy like tossing the bird wildly. Any one have any suggestions on how to remedy this problem?
