Be careful with raw hides. They can cause vomiting, diarrhea, and many other things. I substitute those with beef cheeks. Most dogs do well but my dog for some reason didn't do so well after eating one. But we took her off of chews completely.
So cute that he's loving his new treat, but as @Russian4 said please be careful with those. I've heard a lot of horror stories about dogs who have had bad experiences with rawhides. I myself have never used them, I use Himalayan chews.
