Ugly feminine males...

This doesn't really apply to original topic, but...the discussion of size/build/HD made me think of it...

I took 2 of my dogs to have Penn-Hip tests last winter (male, 65/66 cm, 18 months and female, 60 cm, 15 months).

Results:

Male: .38/.39 - no HD evident at all
Female: .27/.37 - no HD at all

PennHip measures laxity or "looseness" of the hip, which is a big genetic component of HD

This fall, I took the same two dogs for OFA tests - male at 27 months, female 24

Results: Male - Mild HD, left hip (C), Female - Excellent (A1)

The results suggested 3 things to me (hopefully I will have more results as I test more dogs) -

1. It is possible HD shows at later ages (big change from 18-24 months for the male, a surprise - I learned OFA results after I bred my litter - although I knew it was a possibility from the HD present in earlier generations)
2. Size is a factor, since both dogs had similar laxity
3. HD can present with relatively tight hips (it is the same for the GSD) - close to or below .30 is considered very low risk, close to or above .70 is considered high risk - but it changes a little with each breed
