The reason I say this is because she's not even at the full end of her chain.
I can't think of too many dogs I have photographed that aren't fully at the end of their chain, leaning into it.
She is supposedly in top form, and yet isn't even enthusiastic enough to get to the full-end of her chain.

I agree with Bolero a picture is just one dimensional.

Most dogmen are NOT photographers and its hard to get that one perfect shot of the dog leaning into his chain to see his striations in his muscle tones.
