Not Tuff
Color: Black Yellow Phrog, Color: Black Yellow Phrog
Absolutely terrible and not “tuff” at all. My chocolate lab had this thing destroyed in less than two hours. I would not recommend these for the price.

Cute but Not Durable
Color: 2PK Green Leaping Phrog
⭐️⭐️⭐️⭐️ 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.

Cute but not durable at all
Style: Crepe
Cute toy but not a very durable toy for my Doxie. Was ripped apart in less than 30 minutes. She had fun though.
