Purina Busy Bones didn't keep my dogs busy!

I love to buy treats for my dogs, and I like to keep them busy while I am away. Normally I stick a treat in their holy roller toys and they are entertained. But I decided to try out the Purina Busy Bone dog treats, as I saw them at Wal-Mart, and I love to spoil my dogs.

Well, my dogs stayed 'busy' chewing these dog treats for maybe 3 minutes, then they were gone... I was disappointed, but I thought maybe my dogs are little piggies, but I don't know, I thought these 'long lasting chews' would last longer than 3 minutes...

I worry about rewrding my dogs with Purina Busy Bones in the future, I just can't risk that the treats break off in a larger peice to be eaten, as that might cause major digestive issues.
