Cute toys
Color: Purple & Yellow & Green
Cute and great squeaky toy but if you have a rough chewer on your hands, then they are easily destructible.

Fun but easy to destroy
Color: Green & Yellow & Blue
We foster puppies and go through a ton of toys. These soft, latex toys are great for non-super chewers, whether puppies or small to medium dogs. Our 20-week-old foster puppy has had a great time with hers, which still squeaks. She is fairly gentle and enjoys squeaking her toys, but is not destructive. If you have super chewers, these will not last for even a minute. One of our dogs got a hold of one toy after a few days and demolished it in literally 6 seconds. The price is quite high for toys if in this style, as you get three of them for $16, and typically you can get similar toys for a much lower price, but they do have a great squeak and the long necks have really pleased the puppy. I think that for the right dog, these would be great, and I would recommend them, but avoid them if your dog likes to destroy their toys because they are terribly easy to rip apart.
