Not Scented, but Dog Approved

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!

Works great for scent work! Bounce is great for air retrieve!
Size: 2-pack, Style: Duo, Size: 2-pack, Style: Duo
My dog doesn’t know he loves them yet but I do! They are a little softer so when we do air retrieve, I don’t have to worry as much about his teeth! I’m hoping he will learn to find them by smell vs sight. We often play in the evenings and he tends to loose his ball. Love chuck it! Right now, we have about 10 chuck it balls! The tennis balls don’t work for air retrieve! Chuckit does!!! Love the thrower too! Saves my arm!!!!
