My pick puppy has been looking good all along and suddenly when I did a routine "check out the teeth" this week she has a reverse scissors bite. Bite has been fine since birth and the litter was evaluated by fellow breeders at 7, 8 and almost 9 weeks with all bites checked and fine. No other owners have mentioned their pups' bites going off and this is something I have never encountered in my bloodline. I know they say if you're in this long enough you see it all but is there still hope it will go back to at least level? Just wondering if I should get hopes for showing her out of the list of things I want to do with her. Thanks for any constructive advice besides "place her in a pet home" as she's staying no matter what (long story of last of line, bitch had to be spayed, etc.)

At 15 weeks the teeth are just beginning to fall out and you have a lot of growing to do including head structure which includes formation of the teeth and jaws. I would just sit back, dont look again, and wait.

Who knows what will happen. I would keep her and do the things you want to do. See how her adult teeth look. I think someone told be years ago to buy beef knuckles for them to chew on with their front teeth. Supposed to help, but I have never tried it.

I had that happpen years ago, kept her and no puppies had that issue. She was the only one I had ever had with it and her bite was fine at 8 weeks up until about 14 weeks. Two of my very old mentors told me to keep her as they had had a couple bitches each over the years that had that and only one puppy ever produced had it.
BTW Don't get teeth pulled. I haven't heard of that working , if anyone has I would love to hear about it.

Thank you for the "sage" advice. I appreciate the responses. I will try not to check her bite 10 times per day and hope that things will change as she grows. Her baby teeth are starting to come out and I won't remove any or file them down as I have heard some do. Can't see that it would help anyways.
