Dog loves this toy. A lot.
Style: Animal Sounds Babble, Size: Large
Let this be said first. I HATE this toy. It's loud. It's annoying. It scares me in the middle of the night if I walk too close to wherever my prankster dog has left it hidden. Did I mention that it's loud?
Now that that's out of the way, let me tell you a few things about the ball I got for my dog for Christmas 2014. Keep in mind that I have an 80 pound energetic young counter-surfing chew-happy Rhodesian Ridgeback. And the ball I bought was a small size.
As I may have mentioned, he's a chewer. This toy broke in half today. That is, like, a record for him. He's a tube o tennis balls a week kind of guy, and this stupid little ball lasted him (barely) over a year. He just walks around with it in his mouth giving you goofy looks while the ball makes animal noises and they echo around in his skull. Occasionally he tosses it as high as he can and then chases it after it lands on the floor and rolls off (it's an old house, the floors are slightly slanted, don't judge), which is why the ball broke. He tossed it a bit to high and the seam finally gave way. I was initially concerned because of the hard plastic shell, but after a month of constant supervision I realised that he was okay with the ball and stopped watching so closely.
It has also been a source of constant amusement to him. He likes to tuck it away just off of the high traffic areas and just out of sight to his humans. Then, as his humans walk past and activate it and jump 50 feet in the air, there he his. Standing there. Wagging his tail and giving you a doggy grin. You can almost hear him laughing....
Seriously, odds are you will hate this stupid little ball. But, it will totally be cancelled out while you watch as your little buddy does goofy crap with it. Heck, mine broke his 10 minutes ago and here I am, ordering another one, knowing that in a week I'll be cursing again.
Don't let your dog play with it unattended, at least until you know whether or not they are going to try to break it into a billionty pieces and eat it. I imagine that it could break into sharp shards. For some reason though, my dog didn't try to kill this one. Hopefully you're dog will like it as much as mine does. Hopefully you won't hate it as much as I do. :)

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.

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. 😂
