Gundog Training Forum

9mm is quite a lot and with such a gap, it'll never have the correct bit. I once had a pup with such a large gap (although this started to appear slightly later than with yours) and he remained heavily overshot for the rest of his life. Please beware it's a major fault and as such this puppy should never have been sold to you, the breeder should have informed you and if sold to you anyway, it should be 1/2 price. A working dog with an incorrect bite can have problems with retrieving simply because they can't hold on to the bird or have problems picking the bird/game up - my dog did develop his own technique but he always struggled with smaller birds like wookcock, snipe, partridge so from a practical prospective there is logic to why overshot/undershot is a major fault in a gundog.
