Quality product
Color: Blue
Great toy but the holes are very large for the snacks so they fall out easily. I have a toy poodle and it was to large for her, it seems like it is made of good quality materials and would be great for chewers .

No match for 3 month old puppy!
Color: Blue
I was really hopeful this would last a while, but 5 minutes out of the box and my 3 month old puppy has chewed two chunks out of the blue part already - seems this is too soft for puppy teeth, and it specifically claims to be good for puppy teething. 5 minutes of play is not worth paying for. Maybe if the material had been more substantial, this could have been great for high activity level puppies. My pup had no trouble carrying it around, so it wasn't too heavy, and it was easy to play fetch with as well. For reference, my pup is a mixed breed - labrador, poodle, newfoundland.

Best ever dog toy
Color: Pink
This is such the clever toy and actually I think it makes my pup more clever too. The ball is tough enough to withstand excessive chewing. I really can’t say enough good things about this particular dog toy. This will keep my dogs attention for such a long period of time and you can truly just watch the wheels turning in his head as he figures out how to get the food out would buy again and I probably will just to have a back up.
