I ordered three of these and this item is great, I own an 11 week old German Shepherd puppy that loves to chase a tennis ball and she grows bigger every single day. I was afraid that if I got a ball that was 'her' size that I would not be able to keep it as she grows, but these seem to be just the right size, she can carry it around in her mouth just fine - she was carrying regular ones at 7 weeks!
