Size: Medium Chew Stick, Style: Peanut Butter, Size: Medium Chew Stick, Style: Peanut Butter
My pup absolutely loves it and it's helping him with teething. It doesn't break off in a bunch of big pieces, just tiny pieces. He spits out the little pieces thankfully! Very well made and smells appetizing to dogs! It definitely helps clean his teeth & the rest of his mouth!

Mini Aussie LOVES
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
My little Meg loves these chew bones, she sneaks in and steals them from our Golden Retriever and our Great Pyrenees. She chews the orange covering off in minutes and the under bone lasts a few weeks. The dogs steal them from each other all the time, even though I buy them each one. Highly recommend if you have a super chewer, just be mindful the orange cover is easily chewed off.

But It
Flavor Name: Peanut Butter, Size: Medium
My fur baby has his fair share of toys, but something about this one he won’t put down. Pieces fall off the ends once they chew on it for a while.
