My dog Judge is a 110-pound German Shepherd that loves this tire! It is not the traditional ball that dogs like to play with, but it is so much safer since larger breeds might choke on a ball, as it’s easier to swallow! Judge doesn't go anywhere without his tire! From an owner's standpoint, it’s great also since it’s easy to throw and roll as well as last longer than most toys since it’s made of thick rubber! Best toy for the money I have found by far! Judge has the size large 10”!

This is way too big for my dog. I thought it would be smaller when I ordered it.

Great little toy for playful small dogs

These toys are a soft latex kind of material. I would not recommend these for larger dogs who can wreck a tennis ball, or who are rough with toys. The material of these toys lasts quite a while, but does break down in direct sunlight in addition to dog saliva and being left outdoors in inclement weather. My dogs have played with these toys for a week's time with no adverse reactions from the materials. For a better explanation of the toy, see my video. I show a "durable" toy that is at least 12 years old. I show a similar toy to these here, but shaped like a chicken. It is showing the effects of time, and dog love; it was a favorite of my previous pet, and bequeathed to the dogs I now have. This chicken toy will "disappear" soon because its material is breaking down. I highly recommend these toys for dogs who like small toys, soft toys, and toys that squeak. I do not recommend these for dogs who are "chewers" of toys, large dogs who may swallow this toy(it fits in an average woman's palm), for owners who hate squeeking toys, or for a pack of dogs who will bite and pull at this toy. Although it does have stretch, it can be sliced with sharp teeth, and come apart.
