Meh..., I'll stick to fave pig ear chews
Only 4 for $6, idk these don't last long. I wanted to try them because my dogs love being spoiled but I think I'll stick to pig ears at a discount from Petco. They are very hard, some chews crumble or soften as the dogs knaw at them during the day. However these chews didn't last longer than 10 minutes compared to actual no rawhide alternatives I have used. These didn't do that. No upset stomach so that's a plus. The smell was similar to pig ears also, texture was different. No slimy residue w/ it unlike with the regular 100% pig ears. Helped with plague build up but there is still plague on insicor tooth. Probably won't buy again, meh.

bag came ripped
bag came ripped so the chewy pig ears were not chewy they were hard, I didnt even give them to my dog. The worst part is they are not returnable or refundable - what a waste of money
So not acceptable.
