Good product
Theme: Pack of 1, Size: Ball - Large
This ball lasted 15 minutes with my dog before she had it in pieces. My dog is an aggressive chewer and I was hopeful but it didn't work out.

Passes excessive chewer test
Theme: Pack of 1, Size: Ball - X-Large
8 month old English Bulldog worthy. This is Blossom's favorite ball and chew toy. She has spent many hours chomping on this and it has held up very well. Occasionally she shares it with her 4 year old sister, also an English Bulldog. Highly recommend...

Best Ball Ever
Theme: Pack of 1, Size: Ball - Large, Theme: Pack of 1, Size: Ball - Large
This ball makes fetch obsessed Zeus want to play fetch 24 hours a day instead of his usual 22. Perfect size and the mesh design lets him breathe. Plus it floats. Highly recommended.

Theme: Pack of 1, Size: Bumper
this is a great toy for a dog who likes to always have something in their mouth, but it is not super durable. one side has already ripped just from normal use, carrying and tossing. otherwise good toy

Aggressive chewer
Theme: Pack of 2, Size: Ball - Medium
I have bought three of these balls. My very very aggressive chewer, 1-year-old miniature Australian Shepherd, has not been able to tear one of these up. This is the only toy that he has never been able to destroy.
