Oh, right, I forgot. OFA (which has been mentioned multiple times now) tests dogs' hips. KYS mentioned another place that tests hips for hip dysplasia. This would be PennHip: http://www.pennhip.org/

Sue, I'm glad you're taking this all in stride and have returned . However, I'm wondering why you're breeding a Toy to a Mini...? See, while we adore dogs due to their wonderful companionship, it is to my and many other's preferance that dogs be bred to either the conformational standard or used for working (herding, police work, etc.). So, my suggestion is to get both your pups into an AKC dog show and breed them to their own sizes.
