    My Doxie’s Absolute Favorite Fetch Toy – Who Knew Baby Balls Could Be So Paw-some? I bought these colorful baby balls as a simple toy for my little one, but my furry bay claimed them as his own from day one! These small, bouncy balls are perfect for little dogs – they’re lightweight and easy to grip in his mouth, keeping him entertained for hours. No squeakers or stuffing to destroy, just pure, durable fun. If your pup loves a good game of fetch or just batting things around, these “baby” balls are a steal. Highly recommend!

    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.
