⭐️⭐️⭐️⭐️ Cute but Not Durable Super cute toy—my dogs loved it right away! Unfortunately, they chewed the head off within a few hours. I ordered a second one because they were so into it, but the same thing happened again. I won’t be ordering a third, but they still play with their two headless frogs. So while it’s not the most durable, it definitely kept them entertained!

BUY IT!

Style: Baguette

This is AMAZING! My golden retriever loves it with hidden snacks on it or not. I wouldve put some more snack stacking on it, but dotn hesitate, BUY IT, its undestructible and fun.
