For some reason I keep seeing people saying this, that the shoulder should not be TOO angulated. I am speaking mostly about border collies, although "structure", in general, can be applied to any breed. But in my breed, I have never seen a shoulder that is "too angulated".
Not going to lecture, just putting that out there. It is my strong belief that "over-angulation of the shoulders" is a myth in border collies.
Not the best picture or stack, but the face and markings are not too distracting. Over-angulated? Nope, he's just right. How could having full range of flexibility in the shoulders possibly harm this dog's agility performance? And indeed, he has great flexibility of stride, the ability to collect and turn on a dime, and much more.
Anyway, just a peeve of mine that seems to be popping up a lot lately. I think a really great shoulder is kind of rare in BC's so I wish people would appreciate it a little bit more!
PS (edited to add): this does not mean that a great dog can't overcome their structure in some ways, but I do think structure matters, especially with the level of competition and athleticism in the sport today!
PPS here's an agility picture :)
