Dog Approved! Not for heavy chewers.
Color: Basic
The puppy loved it. I wish I didn't have to open it to to turn it on/off or charge it but not a big deal. The case is a heavy foam with a fabric overlay so don't leave this toy unsupervised with your dog because if they get tempted to chew, they can certainly rip this thing apart and swallow chunks of it but really you shouldn't leave your dog unsupervised with any electric battery operated toy. The battery life is good, better than some other rechargeable toys we have for her. The motions aren't super awesome but they are enough to entertain the pup for a few when we want a break from getting bombarded to entertain her with regular old dog toys. This thing is cool and the size color, and quality were as expected.

Fun, durable, interactive dog toy
Color: Basic, Color: Basic
My dogs love this ball. It keeps them engaged with how it rolls, vibrates, and moves across the floor. Moves best on hard floors. The ball is very durable and they have not torn or ripped it at all. I really like that it is rechargeable so there are no batteries to replace. Had provided many hours of fun!

An Ice Cream Cone for Dogs Who Have Never Paid Taxes
Style: Frosty Cone, Size: Small (Pack of 1)
Bought this for my dog thinking it would provide “a few minutes of enrichment.” It became an event.
The second I pulled this thing out of the freezer, my dog reacted like I had personally returned from a heroic quest carrying the sacred treasure of his ancestors. Absolute full-body joy. Olympic-level tail wagging.
The rubber feels sturdy, the opening is easy to fill, and freezing treats inside keeps him occupied long enough for me to answer emails, drink coffee, and briefly remember who I was before becoming a full-time employee of a small furry creature.
I’ve filled it with peanut butter, yogurt, treats, and one regrettable attempt involving pumpkin puree that turned my kitchen into a seasonal crime scene.
Best part: it’s durable enough to survive enthusiastic chewing without immediately looking like it lost a fight with a lawn mower.
Five stars. My dog now stares at the freezer with religious devotion.
