When I leave Nebo I always give him a kong or his milkbone ball. There's a large milkbone and some of that kong stuff'n and sometimes I'll put other treats in there.

I've never had any sort of problem with any of the kong products. But, as others have said, it definitely depends on the dog. Nebo had barely put any dents in his...but Lady can rip chunks out of the red ones.

Those are the only toys or treats I will leave him alone with. I have a huge bin with several different types of rawhide that I give him on occasion. I never leave him with it unsupervised, and he's not the type of dog that swallows it whole. I also have booda bimples, nylabones, and the dental dino which he loves to chew on...just not alone.
