He only eats them if I cut them into smaller pieces with a knife. They are very hard, even with the knife I struggle to cut them. Of course, he smells them and goes crazy, if they were softer they would definitely be our favorites

I don't know, for some reason my dog doesn't eat anything from this brand, I bought him different sizes, different flavors, he doesn't eat any :( (he has at least eaten these specific ones after many attempts to give him this treat) I will take them to the park to see how other dogs react. It seems very strange to me that he doesn't eat anything from this brand.
