Great bounce, loud squeak, smaller than expected
Great little ball with a high pitched squeak and a nice bounce. I recommend going with a bigger size than you think you need. They have the sizes in the discription and I thought the medium size would be perfect for my 45 lb dog but it was a little too small for her. Also my dog doesn’t tend to chew heavily, but I can imagine that some dogs might manage to break through the rubber without much effort because the rubber is soft enough to easily squeeze for the squeak.

Best Balls for aggressive chewers.
I have a bully and shepherd that tear up toys in 30 seconds. They got these for Xmas and it’s been over a week and they are still around in one piece. Very good quality. They have not been able to kill the squeaker.

Large tennis balls
Color: Mixed Color, Size: Large (Pack of 12)
These bald were great for a dog birthday party gift bag. The dogs loved them. They are a little larger than a regular tennis ball and great for larger dogs.

Great customer service
The squeakers broke within the first few minutes of my dog playing. But the customer service has been outstanding.
