Surviving a 8 month old heavy chewer
Color: Blue, Color: Blue
My dog is OK with it but doesn't like it as good as the whale indestructible toy I got her previously. She chews on it a little while and quits. She acts almost like it makes her nauseated. Idk though.... It gets very very sharp! Be careful grabbing it after they've chewed it.

Perfect for my dog that destroys everything
Color: Purple
It’s important for you to know: it’s hard. It’s a hard toy. It’s a bit heavier than normal dog toysx but it’s perfect for dogs who destroy every toy.. I have a 30lb 2 y old baby and they keep her entertained for sure. They are s good size. I honestly love it. My dogs love it too. It was a good purchase :)

Indestructible dog toys
Color: Blue
These are indestructible toys. They do, however, hurt if the dog comes and drops it on your head while you’re sleeping. It is also quite scary when the dog drops it on the tile in the middle of the night. Be warned ;)
