Healthy Dark Colour

Hello, Karstuhl here!

A French scientific study has revealed that pigeons in urban areas who have dark feathers are more healthy than pigeons with paler feathers. They also respond quicker to infections. They even seem to have greater sex appeal, perhaps because of their better health. It is, as yet, not quite clear what the cause of the better health is.

I wonder if this applies to dogs as well. Are dogs with darker coats more healthy than those with paler coats? Are black and tan Shibas, like Mommy, Daddy, and I, more healthy than other Shibas? Do we have greater sex appeal? I hope this is the case.
