Our three lads have different teeth all together and not one appears to be suffering... now.
Ali, our older undocumented lad, came to us with his canines flattened 1/3 down, we were told to stop his puppy playfulness from damaging his champion papered playmates. His uppers and lowers are straight and small. He has so many major troubles (hips and cancer) we have no concern about his small teeth.
BoMe came to us with intact canines that he used expertly to play-fight and frequently cut Ali who 2 years older, was and is so submissive as to allow this and not fight back... poor lad could not do any harm the same way even if he wanted to! To protect Ali, we had BoMe's canines less severely but yet also dulled.
BoMe's in-betweens, uppers and lowers, and those immediately behind the canines, are very small and/or buried by gums. BoMe has so many major troubles (see other topics - he appears on the mend now thank you), we are happy his teeth are not among them... but ugly they are ... thankfully his huge tongue is out, masks the full-gum look, and gives him a lovely boxer smile.
Cody... Cody... Cody, our demanding darling pup, has absolutely perfect teeth all over. They are fully developed but he has such a soft mouth bite that not once has he bruised much less injured his mates or any in our family, even with his fully sharp (and are they ever) canines.
My son wanted a white but we chose 4th generation (Thai) champion Cody hoping he has no genetic defects and can be bred.
About the singing, I am jealous!
About gas times three, .... it will not ever smell sweet .... we really love our lads and do keep our front doors fully open 24/7 ....
