I have two jack Russell's and they both love a good chew. I have been looking for something more natural but doesn't smell awful in the house (why would natural smell so bad, when it has been enhanced by something?). These chews do the trick and fulfill the remit. They don't smell awful as they truly are natural. They last a good length of time. They don't have nasty plastic like some other chews we had tried before. Both dogs love them. Customer service was outstanding with a lovely email to say thank you and you could reply and have a human answer you! Would recommend.
