Looking for some advice. I bought a puppy which was meant to be for showing/breeding. I know the breeder and fully trust her as she knew I wanted a show dog. At 4 months old I noticed he had a undershot jaw. Could someone tell me where I stand with this please? All I’ve been offered is another puppy discounted which I don’t want

Sadly I don't think any breeder can say 100% that a puppy will turn out to be of show quality.  I assume there was no sign of jaw being undershot at 8 weeks?  It may just be a growth spurt and sort itself out in the coming months

Actually a puppy can be 'of show quality' but unfortunately go on to develop a fault that may not be seen early days but which would rule out him being showable.   I have one I bought at 4 months and he looked exactly what I wanted to get me back into the ring, even if just locally.  Not only do his teeth (front) look like skittles, but by 8 months he'd gone lame which turned out to be premature growth plate closure, both front legs to the point that even for his breed, his front legs have more turnout than is ideal.   Sadly an undershot jaw won't get any better.

I guess you have to make up your mind whether to take the offer of another puppy, if you are hell-bent on showing, or live with this pup who I'm sure you love.   I know I did this with my puppy, now just over 10 years.  Obviously your puppy must not be bred from.

The best any breeder can say about a baby puppy is that it has "show potential" at the time. If his mouth was correct at the time you collected him (and of course you'll have checked this because you wanted a puppy to show) the fact that it's changed since is just bad luck I'm afraid. You have a lovely pet dog who could still be outstanding in any of the other canine activities - just not conformation showing, as undershot jaws do not correct themselves whereas overshot jaws can.

Loving family pet (first & foremost) comes to mind.

We are not perfect as human beings therefore, we shouldn't expect any puppy to grow to be fault free either, just my humble opinion, love them for what they are (your best friend).

Thinking on this, and being unable to alter an original post after a certain period of time, if you have room, it might be possible to buy another dog for showing?  But equally, I think I'd go for a slightly older youngster so you would be less likely for the dog to develop a growing problem?  It would cost a deal more however.   Maybe whoever bred your pup ran on a couple to delay choosing which to keep, as many breeders do - and if she knows you want to show, let you have one of the two?

Very true and would remind in the family whatever. He is now 14 months old and still lives with me but started fighting with my other male when he was 7 months old. For this reason, I need to rehome. I've had him castrated in the hope this would work. But now my other dog keeps attacking him.

I've spoken to a few breeders and all said it would be evident at 8 weeks that he was undershot. He's now 14 months and hasn't improved

>I've spoken to a few breeders and all said it would be evident at 8 weeks that he was undershot.

Not necessarily. I've known pups with a tight scissor bite at 8 weeks end up undershot by the time the adult teeth come through. I've never known a pup go overshot because the lower jaw grows for a longer time than the upper. An undershot jaw will never 'come right' but an overshot jaw can.

> I've spoken to a few breeders and all said it would be evident at 8 weeks that he was undershot.

But surely you checked yourself?

If it would be evident at 8 weeks why did you buy him or did you not notice ?

If it was undershot at 8 weeks, your vet would have pointed it out at the pup's first vet check.

As (an abstract) comparison, if I bought a working dog to compete and breed, and it made a noise while working, I wouldn't expect any recompense from the breeder, even though I would not be able to compete or breed from the dog. I know it's not a direct comparison, but breeding isn't an easy game. You can do all the research to buy the best possible, but you cannot expect every well bred dog to be good enough to breed from to better the breed.
