Chew toy
Color: Red
It’s a great chew toy for dogs and definitely keeps them entertained for hours however, it’s not durable enough for really strong chewers. I have two pitbull puppies and in five days he tore the end off of it. I do recommend for medium sized dogs.

Fun ball for my big Golden Retriever!'
Color: Orange, Color: Orange
It's big and has some weight to it in comparison with ither balls that hardly weigh anything. My 4 year old Golden Retriever can get his jaws around it only just! The squeaky is tough to get squeaking especially if you have a smaller dog. My dog is about 100 lbs and can just barely bite it hard enough to make it squeak. Very cute toy and I pretty sure this is going to last him a long time because it really seems very durable! He loves it!
