    Does anyone elses dog have one? Noodle my youngest has quite a severe one, although it seems to cause her no trouble.

    She is the dog in the pic below with my son, you can see she looks like she is always smiling :)

    Just wondered if this will ever cause any difficulties as she gets older? I think she is aprox 3 yrs, its hard to know as she was a rescue.

    Be good to hear of anyone elses experiences.

    Thanks
    Gina

    Billy has an undershot jaw too, the vet referred to it as a reversed scissor bite, as the bite is the exact opposite of a normal scissor bite. The bottom teeth fit neatly over the top, rather than the other way around.

    It makes him look like he is always pouting!

    A reverse scissor bite isn't the same as being undershot, well not really.

    Undershot is when the lower jaw comes further forward that the upper jaw, in a reverse scissor bite, the jaws could be in line, just the teeth sit differently.

    Billy doesn't look undershot in the photo at all as you cannot see his teeth and usually the bottom teeth can be seen if the dog is undershot.

    Some breeds naturally have reverse scissor bites and looking at Billy, is he a lhasa or shih ? His bite is meant to be this way ;)

    I've attached a photo of our Tipsy's teeth which are exactly how they are supposed to be :D

    lol billy is a mutt! :lol:

    no lhasa or tzu anywhere in his mix!

    He is the result of a slip mating between a yorkie and a scottie. His breeder Shows both but only breeds scotties, stupid accident that showed no pups on scan (bitch would have had mismate if there had been any), was a slip mating and early in season. Billy was a singleton and a suprise. Luckily she had a planned litter of scotties he was socialised with from early on otherwise he could have been a very different dog in temperament as some singletons are.

    Neither breeds in his makeup are meant to have undershot jaws and his jaw is undershot. Its termed a reverse scissor because its not severe but it is an undershot jaw clinically regardless. Your right though his teeth dont stick out unless he wants them too lol.

    Both my Chihauhua's have undershot jaws, I think it is quite common in the breed. Adam's isnt too bad, you only really notice if you pull his lip back but Heidi's is quite noticeable.
    She looks quite pugnacious most of the time, not helped by the fact she is a smiler too. Looks sooo funny seeing this little 4Ib dog looking up at you with a full set of gnashers on display!!LOL

    All of mine are undershot by a good couple of centimeters, but they are supposed to be. As previously mentioned a reverse scissor is completely different as the teeth actually touch - this would be considered a fault in my breed as there needs to be a visible gap.

    Some breeds are meant to have it but prognathism is essentially a deformity that has been selectively bred into them. There is the side often puported that it provides a stronger grip but I can't really see a could reason why any animal would need one.
