Caspar: same black coat; slightly taller than Edward.

Coincidentally, the last five foster greyhounds have been black (in order, Barney, Pete, Bruce, Edward and Caspar, shown above). And six of the last seven (Lou). They get to go on long walks. I'm a keen rambler. People - neighbours, locals - nod, acquaintance-like. Now, these black dogs might have had variations; white toe-tips, or a slightly larger or smaller chest patch, or floppier ears; but these details are generally not significant enough for the average dog-spotter to notice. So they think they are all the same dog.

But the five black greyhounds were different sizes. Some greyhounds can be confused with whippets, while some are the Clydesdales of the greyhound world. One chatty passer-by insisted one of my greyhounds - I think it was Bruce - had grown a couple of inches in a month.
