...what "ZW 78" means? Is it something to do with hip or elbow ratings? Thanks.

I think it is a rating of parents that are breeding with chances of getting hip problems ie ZW 78 (low risk for hips)

Thanks, I thought it might be for something like that but wasn't sure, so thanks for passing that along.
