Rex, photographed this morning while walking his human in Village Green. He is a Bavarian Munsterlander crossed with, of all things, a Shar Pei: very, very large, very friendly, not as wrinkly as you might expect.

I’ve never heard of a Bavarian Munsterlander before but it’s surprising how many breeds of dog can have brindle colouring.
I think it’s caused by a recessive gene that interferes with the base colour, like ginger hair can be caused by a recessive gene that masks dark/black colouring. It’s probably a lot more complicated though. . . .
