I've had this in my mind for the past few days while I've been setting up and running the workshop... and there really isn't much to comment on. It's a thoroughly good and characterful drawing.
What follows is personal preference, and not a criticism.

Shiny and not shiny (like this one where the reference photo was taken in a studio with two light sources, left and right)
That presents a potential problem. Unless one was a key light and the other a weaker fill light, I'd expect the two to remove dark shadows - or possibly
all shadows. That needs compensating for in the drawing. Seeking a similar photo online (with a single light source) could help a lot with that.

I think the lighting is probably the cause of what, in my opinion, is a black coat that's too light. The dog is obviously black and white, but the lighter black areas diminish the effectiveness of the highlights. That causes them to look a little flat. But, as I said, that could be due to the lighting.
Other than that, there's not much to say. I feel the neck and chest is too long - because it competes with the head for attention. Although its minimal detail in the white front does help to counter that. It's actually only just more than half the height of the drawing, but it appears to be longer, and I still feel it's too long.
Other than I'd like to see less neck and more three-dimensional shaping, it absolutely does its job in displaying this lovely Border Collie. Full of life, with shiny, alert eyes. Lovely!
