Doggo loves LOVES these. However, I have to keep them in the fridge otherwise they seem to soften up (in the southern Heat I guess). In the fridge they stay hard so he has to work a little more to get through it. My gripe is about how annoying Amazon is with the pricing of this product!! I have gotten it for $20.99 for the box of 36ct regular size and other times it’s highly inflated at $36.99! So definitely look around before buying on here. I do occasionally get a few boxes when they’re a good price on here. Other times I find them cheaper on Chewys.
