Front angulations - Page 4

Look at the length of upper arm of the dog and tell me, relative to length of shoulder blade.
Is it long ?
Is it slightly short ?
Or is it short ?


Bear in mind standard says scapula and humerus are approximately of equal lengths. Experts say humerus should be slightly longer than scapula.

Which is longer this upper arm

 

Or this one

Comparatively, the top one has the longer upper arm. The bottom one is more equal to the scapula.

My thought, if I am understanding correctly! You are a wonderful teacher! It must run in your family!🤓

Correct beetree.
I personally think second one's humerus is even a bit shorter than the scapula.


There was a question prior to the one beetree answered, any one likes to answer?

I think that in cases where the actual 90* angle is achieved, the dog loses front reach and we see, instead, a restriction in shoulder opening. Look at some of the pictures of recent VA dogs in movement.

If you are looking for GSD reference books on the topic, the Fred Lanting book is very good in its discussion of structure. Also, Winn Strickland's book, although an older book, has some excellent conformation and movement discussion--if you can pick up an inexpensive used book, it might be worth reading. And the book recently printed by Linda Shaw is packed full of good information.

Here's some good links:

Very interesting Christine about the 90 degrees. After you told me about Linda's book I contacted her and got it beginning of the year

Think of the mechanical function of the joint. No matter what, the joints of the shoulder are going to have a maximum amount of opening, right? I mean, just based on the actual structure and mechanics of how those joints are made. And to get that 90 degree angle, what is different from the shoulder with the 98 degree angle? What actually changes to create that angle of change? If the angle is more open, obviously the joint will be able to open further.

I wish I could study the joint itself, how it is set and what the opening capacity is. I know my joints have a certain limit of opening after which they would not open unless you split the bones out

Let us compare the joints and front reach of both these dogs, but please Rupesh interact with us so we can know if you're following or not
