Everything I read about Basenji teeth indicates they are very strong. My 5 1/2 year old female basenji has started chipping, splintering and losing her teeth. At first it was just one impacted rear tooth that needed extraction, then she splintered an incisor, and now there are 2 front teeth almost missing (broken off). She does NOT chew any hard bones, not even bully sticks, per her vet. On occasion she will chew and rip up bedding and softer materials. Once she chewed through an extension cord, but we do not consider her a 'chewer'. Any insight into what could be causing this would be appreciated!!!!!!!
