I wasn’t sure how my dog would like this since it’s stick shaped instead of the typical Y or T shaped bones. She was apprehensive at first but eventually loved it. She’s on her second one now. They don’t last quite as long as the name-brand nylon bones but she loves them the same and they’re a better price.
