A hit for Border Collies
Color: Blue
Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.

Dog destroyed it the evening we received it. It was a cool toy, though. Too bad it didn’t last longer.

Best toy every
Color: Orange, Color: Orange
My husky loves it. It's one toy she's not been able to destroy yet. She plays without when she's outside in her lot and will play for an hr at a time. She loves it moves and bounces instead of just tossing it and letting her fetch. The battery life is really good. We charge it about twice a week. It's quiet, so she loves that. It's perfect size for her.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.
