Our very fussy Havanese absolutely LOVES these sticks! I had to find a new product after the USA-made chicken wrapped rawhide sticks were no longer available. It is very difficult to find a quality product made in the USA & while these are made in Cambodia, they seem to be made under very strict standards. I was also impressed that this co. claims it has never had a recall of their products. I also relied on the many, many excellent reviews of past customers. Our Teddy gets a stick every morning & then will wait by the pantry to get an additional 1 or 2 or more throughout the day! He usually does not eat the rawhide, just chews it up a bit. He is in love with these!! He also has a sensitive stomach & these have never bothered him one bit. His teeth are also quite clean from using these!

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.
