My 12 year old dog was never touched these treats... that is, until I had to put him on steroids (prednisone) and anti-seizure medications (phenobarbital) that made him ravenously hungry! Previous to his medications, he would turn up his nose to any of Science Diet's dry treats - they weren't palatable, were too hard and dry, and were hard to chew into. Now that he's on his medications, he'll eat them, but with no real zeal. He jumps and begs for other treats, but simply carries these dry, hard treats onto his bed, where he eats them at his leisure.
So, if you have a chowhound who will eat anything, go for it. That said, if your dog has dental disease, I'd avoid them - these treats are so hard and crunch so loudly, I worry it actually hurts my dog's teeth to chew on these.
My dog's review of this treats palatability: two thumbs down.
