As I ' ve mentioned many times before , Fergus is having a tough time teething . When two of his baby canine teeth refused to fall out when the adult teeth came in ( for over a week ) , I decided to see what the Vet recommended . So , he was to have some teeth extracted , he ended up needing 5 baby teeth removed .
