Great value
You get so many in the package. My dog gets one each night after dinner as a “tooth brushing”. He’s a big greyhound and these are thin and smallish, which is great for smaller dogs, but he loves them anyway.

My dogs favorite
These are my dogs favourite treats at the end of the day. I used to buy the small packages, but im so glad i just discovered the large size. He waits all day for these and he'll even sit by the drawer theyre kept in throughout the day hoping to get one. They smell like real food (not strong though) and one of these lasts him at least 20-30 minutes. My dog is insanely picky when it comes to chewing sticks so im glad hes obsessed with these. He'll first chew off the chicken wrapping around the rawhide, then eat the full rawhide afterwards followed by a huge nap. They tire him out which is perfect because hes a huge chewer.
