I have seven yorkies ranging in size from 2.5 lbs. (14 week old pups) to a whopping 7 lb 3 year old female with the rest of the crew fitting between. All of my furbabies chew Bullies daily -- they are the best chewies I have ever offered to the kids. I purchase in bulk off ebay and they do NOT smell, are not greasy and DO NOT cause any stomach upset or diarreah.
If I only needed a few, I would buy from our very own Kathryn V --
