OMG the Crested with perfect coats, yes, I love the pony look. Love. In general, not interested in the breed, but wow.
Does it have to be breed specific?
I'm a sucker for red and white dogs. Brittanys are the only dog I in the Sporting group I would willingly have.
Brindle dogs. My dirty little secret is that I want a brindle Chihuahua.
I prefer prick ears to floppy ears, but rose ears make me smile. Josie's ears tend to lay hound-like, but sometimes they rise to rose-like (not perfect rose, because they're bigger than average pit bull ears), and that's delightful.
Tails. I'd be drawn to any dog with a stand-out tail. Especially fluffy tails that sit over the back.
Lots of white markings, but not a mostly white dog.
A nice, thin, symmetrical blaze.
I love generic collie-type mixes, although I'm not interested in a collie or other herding breeds.
I love the sharp look of a schnauzer (good coats, not weird curly coats), and I love grooming them, but I won't have one.
