I have a six month old German Shorthair that i'm having trouble with. This will be my third shorthair that i'm training but i have never had one that killed the birds. I had short flight quail that my dog would point, and upon my flush and shot of my starter pistol the bird would run out of gas and land. my dog would chase and retrieve but as soon as he picks the birds up he crushes them. . . every time. . . he doesn't try to eat the bird, he just bites down hard one time and ruins the birds meat. I don't know how to correct this behavior without turning him off birds.
