I don't have Min. Pin, but when my husband and I choose a puppy, its been always the biggest. So far, none of our dogs were sick during their life span.
Well, my stepfather used to have poisonous snakes.
He got bitten by his snake, even though he had them since they were babies. Anyway he tried to feed the one snake (2 in one terrarium) which didn't really wanted, so the other one joined...
