I used to breed and show Siamese cats, and I bred first for temperament, next for health, and only last for conformation. Had one champion, just the same.
Lots of folks weren't that picky and bred just for looks. There were plenty of mean, sickly Siamese around.
I worked 3 years for a vet nearly went into the field... toy poodles IS a good breed.
He's been gone more than five years, but I miss that little guy every day.
