a bad mouth can be correct in a breed ing progamme,you just got to came shaw that the dog with the bad mouth not to be breed inbreeding or line breed,the best to do a out cross.
then watch that litter grow and watch the sign and keep records of the puppies and the dam,both pearnets got to have the same gene to produce the a puppie with a bad mouth.
but you will not know if the dam is a carrier of the gene beacuse you cannot dna that problem at the moment.
i was told bye a top gentices not to through the dog out with the bath water,if thats just 1 fault to many good ones then put the dog into a breeding progamme but to watch the results and tell the truth.
some judges are hot of this in the show ring some will over rider the problem if the dog has better quailty,
like you say it one fault.
