My 9 month old chi has 5 normal toes on his front paws. although on the back of his front paws sort of at the bend he has another thumb like pad. this is on both feet, is this normal? just wondering because he is sapposed to be pure bred. also his baby fang teeth didnt fall out and they are right beside his adult teeth on top. his gums are normal color and all they dont seem to bother him does he still need them removed?
