Causes of overshot jaws in pups

My BC bitch had her second litter of pups six weeks ago. In her previous litter one male pup had slightly overshot jaw, and now in this litter the male pup again has this time quite severe overshot jaw. Neither the dog or the bitch has any occlusion problems, but since I've read that malocclussion is at least inpart genetic Iwondered whose more likely "at fault" the dog or the bitch? Any way except of courseto mate them both t o different partners, any way to find out?

It's called over bite, and under bite. Undesireable in the show ring for your breed.
They want a scissors bite.
Most likely a genetic fault passed down.

So... You had a pup show up in your first litter with a genetic fault, and then went and had a second litter?

Quality breeding at it's best.

Tori, truly your snark astounds me sometimes.....

If one slight overbite was the only issue in the first litter, then I'd say OP did ok. It may be a dq in the ring, but if these are a working bred litter as I suspect, for the breed and it's job, it isn't going to make a big difference. Why throw the baby out with the bathwater? One fault could have been pinned down to a development/embriogenesis issue and had nothing to do with the dna passed from the parents. Malocclusion in particular can be casued by xrays (ie for number count).

Now that there have been two affected puppies, though, I would suggest it is an inherited issue in these two dogs' cases. So I wouldn't recommend breeding them again. If you have good reason to breed a third litter from the bitch, I'd look for a new stud who has the cleanest lines available. Ask about all his offspring, parents, siblings, etc, and if you can't get answers, don't risk it.

If I am not mistaken it is a polygenetic condition. Meaning both parents carry the gene. So by finding another male you may or may not throw it again.

She could produce it again, sure, even with a new stud. The reason I suggested a new stud is because they usually have much more offspring on the ground with which to compare the prevelance of traits. Easier to track and make educated guesses. Does that make sense? Unfortunately, they probably have not marked the dna of this yet so there is no real test.

Googling "mode of inheritance" +malocclusion will give you, OP, some ideas of how it is inherited.

Hi everyone. Tnx for all the replies. I have decided not to breed these 2 dogs again. They will both be fixed early in the new year. My vet is leaving on holiday tomorrow, so have to wait for him to return. The bitch will off course be given contraceptives in the meantime.
I really did think that first pup was just a once-off untill tonight I saw Don's jaws didn't match and I knew I had a problem.
These are working dogs, no show dogs in their lines. There are unfortunately no other studs in my vicinity to whom I would breed my bitch, I'm not being snarky, just picky. My name is also on the line and I don't want to breed inferior dogs. Mom and dad are both physically impressive dogs, not just me, a lot of people have complimented them both as well as their daughter. I will definately do some research in the meantime just to satisfy my curiosity.
Tnx again guys.
