Bigger Than Expected
I bought two of these for my puppies. They are of excellent quality. They are much bigger than I had expected. The female puppy is more likely to chew it then the boy. He seems offended that I bought him a binky. Ha!!

My dog's favorite toy
Not the best quality but my dog loves them so what choice do I have? The queaker breaks instantly. I have to buy one every couple months because they get kind of deformed after a while. Would be nice if they offered a discounted 3 pack.

Right size for medium size pet.
He loves it. It is soft and he has not tried to destroy it. Squeaks and just the right size. Medium size dog. Very satisfied with this purchase. He loves toys that squeak. Not too big and fits perfectly in his mouth.
