Nice toy for puppy to chew
Nice puppy toy to teeth on but I would have given it 5 star if only it had some crinkle or squeak to it!

Short term fun ending in stuffing everywhere
My dog loved the toys, from the start he grabbed them and ran off to play. However the quality just doesn't hold up to a 7 month old 42 pound mixed doggie. The star toy broke immediately and I had to throw bits of the plastic away. He did enjoy ripping the other toys and pulling out all the stuffing. I did not enjoy picking it all up on the yard. For the price it was OK, but didn't last long and needs supervision for the inevitable destruction. At least he enjoyed them while they lasted, which is why they got 3 stars instead of 2.

Puppy Love..!!
My 3.5 months old puppy actually likes chewing on these toys - both wet and frozen or just dry. A good choice! The puppy hasn’t attempted to chew up any other “off limits” items. This puppy is a large breed weighing in at 26lbs and the toys have held up. The product is built to last!! Thanks for a rough and tough chew toy!

Great for teething pups
Great for puppies that are teething or just bored and like biting. Multiple shapes to get them interested and keeps them busy. Also helps their sore mouths. Just get them wet and put them in a freezer bag. Rinse and repeat
