roybo 2,873 Posted February 15, 2018 Report Share Posted February 15, 2018 Undershot is when the teeth of the bottom come in front of the top. Like a bulldog. Overshot is when the top protrude forwards so there a gap between the upper and lower ,goofy if you will. 2 Quote Link to post
skycat 6,172 Posted February 16, 2018 Report Share Posted February 16, 2018 It would be very unusual for a lurcher to be undershot: far more likely in terriers, and one of the main reasons undershot terriers lose teeth engaging their quarry. Slightly overshot in a lurcher isn't a problem, but if its more than a few millimetres it could affect the way they bite and by doubling up on the problem you could end up with the pups being much more overshot than the parents. Be interesting to see photos of both dog and bitch: their mouths, that is, in profile. Note: sighthound and lurcher pups often appear very overshot as they are growing, because the top jaw grows more quickly than the bottom jaw. Once had a pup who was a clear centimetre overshot at 16 weeks old, but by the time she was adult she had a perfect bite. The same went for one of her aunts. 1 Quote Link to post

But also, only one of the pups was any good out the litter but I don’t believe that had anything to do with the bitch. These were sheepdogs though not running dogs so the need for a good mouth isn’t as vital as a running dog. 1 Quote Link to post

The defect will be hidden for a generation then full nests of defective welps tight mouths overs. Unders crowded mouths none good for a animal full stop.find a good quality animal .atb bunnys. 2 Quote Link to post
