Elbow open - Page 2

Mr. Lanting screened forequarter bones of a very good specimen in action, this is a front assembly reliable representation as it was screened.

Notes:

1. This is an American showline dog, probably Sunsiver would remember dog's name

2. Please pay attention to how good the open of the elbow ( less good than Xeph's)

3. Step is correctly close to ground

4. Front reach is very good

5. This one is very important for future use, pay attention to front upper arm bone shape, it is almost straight with minimum bend along its axis/length, and fore chest development is minimum.

This is one more sketch of forequarter assembly by Mr. Lanting

 

This is a picture with froequarter assembly tracing of a West German Showline by Judge Piero Alquati from Italy

This explains why German showline has superior fore chest development. Because the front upper arm bends outward  pushing the chest to the out (fore chest development). Is this a better thing? Is it even good?

This is a tracing for Vegas's shoulder bones, I have it on my computer but don't know who made it.

'This explains why German showline has superior fore chest development. Because the front upper arm bends outward  pushing the chest to the out (fore chest development). Is this a better thing? Is it even good?'

The dog is crouching in front same as the rear. No it's not good.

What do you think?
While Germans developed better angled front upper arm they gradually indroduced a bend to the bone which increased the fore chest development. Whereas the American showlines as well as the work line GSD maintained a straight front upper arm bone but remained steeper.
This bend is what causes no-elbow-open, and maybe no-close-to-ground trot.

What you think? does it make sense?

That last drawing is not correct. The upper arm is a very short bone. The scapula is longer than that pic shows.
I don't think the WL breeders 'selected for upper arm angles'. I know I don't. I do select dogs with extreme athleticism over dogs that can't demonstrate great agility. So the 'angles' are what they are because that is what makes an athletic dog.

Yes could be somewhat wrong,
I understand, work line breeders mostly do not focus on conformation (they have no conformation agenda) so shoulder bones were less affected

The skeleton over the SL is way wrong. The upper arm is absolutely too long and the point of the elbow is off, as is the point of the shoulder.

Joanro: your last comment is about the last picture, correct?

What you think of the picture by judge Piero Alquati?
