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 ;)
