Well, the breeder I got him from, like I said, is a VERY trustworthy one. She has lots of land in Dade City here in FL, and the puppies are bred at her house. She has an air-conditioned, completely flea free kennel on her property where she keeps the puppies, and they have lots of human interaction.
She also gets puppies from breeders in other states, and is VERY against puppy mills (as am I) so I know he has a good pedigree.
His daddy was 3.4lbs and his mommy was only 2.9. He was the smallest in the litter, and the vet told me maybe 3lbs if he eats alot, which he doesn't.
I wanted to keep one of the puppies he breeds, which is one of the reasons, but at the same time, I've always wanted to get into dog breeding, so I guess this would be a good way to start instead of jumping right into it.
I have a friend, Alex whose parents breed Blue Heelers (Australian cattle dogs) and they told me that after they studded their male the first time, he became very agressive to female dogs, which I'm worried about, because I have a female corgi. I also take him when I visit my mother, and she has two female chihuahuas and a male and a femal black lab, and my little guy doesn't know he's little. He likes to pick on other dogs that are bigger than him.
I'm afraid of doing it on my own, I definately want to go through someone who knows what they're doing, and I didn't even think of going through my breeder. She told me that she breeds them for pets, not shows and breeding, but she doesn't mind if you decide to breed them once or twice, so maybe I'll give her a call.
