Not long lasting for a chewer!
Size: Medium
These are massive! I have a golden retriever puppy and she chewed through the yellow ring very quickly. They keys are much more durable.

Great interactive ball !!
Color: Red
I have an 11 month old golden doodle and she loves this ball! It keeps her attention for a good amount of time I have been using it for times where i absolutely need her to be occupied and so far so good! I was worried she would chew it up but that hadn’t been an issue it seems to be very durable! And so for I have charged it up one time and she has had a few plays with it i should probably go ahead and charge it but lasted good amount! Def would recommend also loovveee that it doesn’t play music constantly ! One main things i was looking for have a few moving ones that are so fern loud I rather her not be occupied 🤣
