Hi Bobby dog,
I haven’t seen those before, but have found a number of chews marketed as Rawhide free. Indeed labeling products as rawhide free is a popular marketing tagline!
I found some labeled “Not Rawhide” that look just like untanned cattle skin. When I asked the company what tissue the chew was sourced from they said it is sourced from skin but it isn’t rawhide because it is skin from the head of the cow whereas hide comes from the body of the cow. Apparently you can have your cake and eat it too!
