My mal really likes this. It cleans her teeth and I wedge treats/peanut butter into the teeth and down the middle. Might help? Good luck!

I have quite a few of these as well.

These have lasted months, but I don't leave them out for him all the time either.

I hide treats in them, fill the middle part with peanut butter, and freeze them.

They also throw well (after he gets all the filling out) so works great for fetch. He does shred them though, but they are worth the money vs shred time imo
