my g/f mentioned 'needle teeth' and that the baby or needle teeth would fall out with time to be replaced by the adult permanent ones. I couldnt remember any such thing with my first dog (it is 20years since he was a pup mind you!) and of course rubbished her claim as rubbish to my horror i found the following today when trying to back up my stance: Retained Deciduous (Baby) Teeth in Dogs looks like i have some humble pie to eat! but seriously what are peoples experiences with puppys teeth falling out and teething etc??
