When I first received the package I was concerned about the small size of the crisps & the package itself. Not to worry! They are rather thick, and I had to half them for almost all of the dogs. They must be delicious because the dogs all gather around the corner of the treat table with the chicken chips! It takes them more than 2 seconds to chew, as well. I’m definitely reordering.
