Bought these small balls as the first real ball for my 3-month-old Boston Terrier puppy He loves it! Right away he picked one up and carried it around in his mouth all day Perfect size for a tiny pup, bounces well, and he’s obsessed with fetching it Holding up great so far during teething Highly recommend for young puppies -simple, fun, and a big hit! 🐶❤️

Best Dog Ball!!

Style: Ultra, Size: Small (2 Pack), Style: Ultra, Size: Small (2 Pack)

Our pug has been obsessed with this ball since we gave it to her — she even slept with it. Somehow it’s still in one piece, which never happens. Easily the best dog ball we’ve bought.

Difficult to destroy. Bounce really high.

Style: Squeaker, Size: Small (2 Pack)

Bought as a gift for a friend's small dog who dismantles tennis balls. He loves them. I have many years of experience with the product (in a larger size) for my big dog. He always had one either in his mouth or near him. They are pretty much indestructible.

High quality, wish it was just a little smaller

Style: Squeaker, Size: Small (2 Pack)

Love these. My dogs would play ball all day if I let them. These are very durable and bouncy. Love that it’s washable. They would chew up the small “tennis” balls to pieces so I love that they can’t destroy these. My only criticism is I wish these were just a little smaller (like the size of the small Kong tennis balls). My dogs can carry it in their tiny mouths but they can’t get their mouth around it enough to chew it to get the squeaker to squeak, which is their favorite thing.
