Nice dog toy but batteries were bad
Style: Blinky Babble, Size: Small
Very cool product as we already had the blue babble one. Our puppy likes to watch it flash and make noise when she touches it. However, upon opening the item the same day we received it and removing the strip so it would turn on, it worked for less than a minute. After taking out the bottom screws, my husband saw corroded batteries. We are disappointed that the intact batteries were not good. Luckily we had ordered a 10 pack of batteries at the same time so were able to replace them and give the toy back to our puppy to play with. Shipment was fast. Item is very durable and both our dogs will have fun with it.

Dog approved!
My dogs love this. This is the 3rd time I have bought them. They are entertained for hours and keeping their teeth strong.
They pay me no attention when they have this toy. 😂

Our Dog Loves This One
We got our dog two nylabones and this benebone and he really prefers this one. Like the nylabones he barely even looked at, but he loves this one so much it's starting to splinter off a little. Apparently it can just be sanded down again but I'll probably end up getting more of these so that we can switch them out. I noticed that the shape also helps him be able to handle it with his paws.
