Good chew toy for an aggressive chewing dog
Size: Large
Well built for an aggressive chewing dog. I wouldn't say indescribable but it has lasted longer than all other chew toys he's had.

Ball is heavy due to solid construction
Size: Large
Just received the large ball. Construction appears to be excellent and time will tell with my aggressive chewer. That being said I ordered the large because our Mini Goldendoodle loves playing with our daughter’s dog large ball. I may not have read description close enough but ball is solid and weighs a considerable amount. Our dog soon learned to pick it up but I’m just disappointed that it isn’t hollow like ones our daughter has.

Love this
Size: Medium
My dog is a beast and loves to shred through any toys we get him but with this it’s keeps his teeth busy and off the furniture and there is no signs of any damage. Super high quality and perfect for any fur baby that’s loves to chew
