Tuffy toys in general are great and they are a pretty good deal on Amazon. They are not indestructible, and if your dogs use them as chew toys they will eventually break through. My dogs have had this Armadillo since Christmas (and they do chew on it some) and the only thing missing is an ear. They like to play tug-of-war with it a lot. This is a bigger toy, but even my forty pound dog plays with it. I would not recommend this toy for dogs smaller than Border Collie size. You can make these Tuffy toys last longer if you don't allow your dogs to chew them--when your dogs starts chewing on non-chew toys trade them for a chew toy and when you catch your dog chewing on a chew-approved toy reward them for chewing. Eventually your dog will catch on and realize that if they want to chew there are certain toys that are allowed for that. In addition to being a great play toy this is a pretty cute toy too!

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!

Great toy

Color: Black/Orange

This brand really makes durable toys. They outlast every other toy my dogs have. One dog loves to get the squeaker out of any toy, but he doesn’t rip this one apart. Obviously it won’t last forever, but no toy does! Some other brands of toys only make it a day or two, while these last months to years.
