My Golden Loves
Size: 2-pack, Style: Duo
My 8 month old Golden Retriever loves these. It is also one of the few products she cannot destroy. They smell as described and she loves to chew them and play fetch when. She can chew these easily without destroying them. Overall good value for the money for my Golden

If they squeaked, they would be the perfect ball!
Size: 2-pack, Style: Duo
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in plat time. And they are keeping him busy at home - that’s a good thing. The scent is subtle but strong enough for him I guess because he loves gnawing on them. If they had squeakers, they would be absolutely perfect. Hopefully Chuck-It will see an opportunity for that down the road!

Most durable fetch balls I know of.
Size: 2-pack, Style: Duo
These balls are the biggest balls of them all. Well, not the biggest, but the best. Every other ball she would chew up in short order and I'd be throwing her a floppy piece of rubber. She just wants to fetch, but if it's not bouncing, she can't catch it on the bounce. Got these balls in July and no damage to them. I just ordered another pair, but only because the other two somehow got stuck up in trees. We have some very old and very large oak trees so not so easy to retrieve. Hope they somehow drop someday. But in the meantime, Lassie will be happy with her new ones. Very highly recommended!
