Durable for large dogs
Size: 3.5"
This is adorable ball. I have a 90 pound Dog and is still intact. I’d like to use it at night when I throw the ball because it lights up my Dog likes this ball over any tennis ball. It’s chewy and a little spikes massages there gums. I bought this ball 9 months ago and he plays with it every day. The light still works.

HE WON’T STOP PLAYING!!!!! Ha Ha!
Size: 3.5", Size: 3.5"
Just when I thought I couldn’t find a toy that would let me watch a 2 1/2 hour movie without interruption…. This came along!! I had to hide it overnight, but he saw where I hid it and he whined for 20 minutes until he finally went to sleep and they say dogs don’t have long-term memory well, this one as soon as I woke up was sitting right by the closet where the ball was hiding, he hasn’t let it go since ….the disco lights are fun, especially at night!!!The only thing is he’s biting the little spikes off but at least he’s spitting them out which is a good thing. Highly recommend for hours and hours of enjoyment plus it’s very bouncy.

Best ball ever! My dog loves it...the only improvement could be made is a tracking device, because when he loses it he is a lost little doggo!

Not what I received last time!
Size: 3.5"
I ordered this the first time and received a blue spiky squeak ball with LED lights when bounced. We loved this ball - its squeak was great, the bounce, durability, and flashing LED were perfect. Eventually the LED failed, but overall we loved this ball!!
So I ordered a second - this time I received a yellow spiky squeak ball (with an insanely loud obnoxious squeak!!) that has no LED light. It’s still a great ball and my dog loves it. But it’s not what I was looking for since we like to play with the ball at night and need it to light up.
Durability - 10/10, it’s very sturdy and feels like it will last a long time despite my dog being a heavy chewer. And my dog absolutely loves its obnoxious squeak!
