Ibrahim you often talk about reach and efficiency on the lines of the something like the big flying trot so adored is efficient.

That is incorrect, I believe like most people that comment on that point you confuse power with efficiency.

It is not me vk4gsd, those are the teachings of the experts who wrote books on angulation and movement, it is also the standard. I did not invent this myself, and I am learning, I too have doubts about this theory, somethings do not add up

Roger that, I have only read your posts not the books. The posts are mostly pure anatomy.

The question of efficiency at trot, evidently the holy grail of gsd breeding, won't be answered by studying skeletons although the skeleton definitely distributes the load.

Lol, we again have some good spirit on the forum

~quote by vk4 from above

If the skeletons are understood to be examples of what to do, and what not to do, then this is a way to validate correctness of a standard when searching for the ideal. The ideal is the holy grail of conformation, that it should and will always be true for a working dog, that "form follows function." My two cents. Clever

Tracing both dogs bones and joints in full reach

In first drawing there is no guessing or possibility for mistake as it was radiograph tracing.

2nd drawing is my best guess for location of joints and positions of bones ( I could be wrong).

OK and how do you propose skeletal details as outlined above are assessed under trial conditions. They can't and they won't. Tracing over the dog by hand on a still photo is very subjective and error prone and highly dependent on the picture frame used and the free hand of the trace drawn.

The harder question is why the out of proportion emphasis on a specific stylised trot in attaining this proposed ideal - who's ideal and what is this function that it serves.

What are the criteria you are measuring the dog against.


by Ibrahim on 23 February 2016 - 23:02

Let us have a look at the angles and compare with our previous expectations/guesses

2nd dog shows better shoulder open and better elbow open

Front upper arm length is approximately same.

Do that under trial conditions.

Again I ask, why is the trot deserving of so much attention as a breeding assessment tool?
