Belgian Malinois approved
Size: Large
This ball was the perfect choice for my 8 month old Belgian Malinois. Should last for years so far it has survived all her chewing needs. It’s the perfect size so I don’t have to worry about her swallowing it.

Good chew toy for an aggressive chewing dog

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.
