Empty Deer Hoofs- how long can they be kept

Just wanted to know how long a Deer hoof could be kept, it was stuffed when we brought it last week, Beryls completely empted it and seems to enjoy chewing on the empty hoof, was wondering do I need to stick to the same week long rule like with bones or just leave it be?

Sorry have never come across deer hooves, guessing it would be similar to a deer antler but they are a different material. Dont know how long they would keep for.

Really as long as you want, why not refill it for her!

the outer of a stag bar and a hoof are basically compressed hair the same as our finger nails so really should last the same as a stag bar as ella said try filling it your self
