Yeah, but brindle isn't really stripes... it's more a tortoise-shell colouration. Some feral half-coyotes have stripish marks, and some African wild dogs have stripes. By and large, dogs do not tend to stripes, though they do tend to the sharp delineations in colouration that are typical of stripes-- they're just not striped. They're masked, saddled, and socked. Personally, I tend to think a dog's markings are more important socially than for any other purpose. This is why their markings are so dramatic in the areas to which dogs pay attention: the eyes, the brow, the legs (length of), the tail (dogs wag their tails to alert each other of their presence-- hence a light-coloured, feathery underside to a dark, sleek topcoated tail). Some hyenas do have stripes. Dogs are among the most morphologically adaptable of all species on the planet (put a toy pug and an Irish wolfhound side by side, and remember that there is no reason why this pair cannot produce viable offspring, if you want a forcible reminder) and they can and have adapted to, well, just about everything. Sorry, just a wolfdog's human here-- strange
