We have a German Shepherd puppy and he loves his Bully Sticks. I like the Red barn ones because they don't smell as bad when he chews on them than other bully sticks. He is a heavy chewer and these last a couple days each for the normal 12" size ones. That being said, We usually buy them the two packs in the store but they had a good sale online so we decided to try and order some. Sometimes in store the sizes of the sticks vary a little bit and that is fine but the sticks we ordered online were really thin. They were the right length but with just a little bit of chewing my puppy could chew right through. I guess these were the reject sticks so that is why they were on sale. Like my title says, great product, but I would buy them in the store, not online. That way you can see what you are getting.
