Aw, Charley, I am so sorry about Kasey. I know that was rough on you. I hope that Kasey II has a long healthy and happy life with you. The previous breeder should be ashamed of what they did to you, your family and Kasey. Never, ever get a puppy younger than eight weeks old and always be sure you get a health certificate. I raise a very few chihuahuas (only 1 litter a year, 3 to 4 puppies) and never let them go too soon. Besides that it's hard to let them go, even to a really good family, like yours. Hugs
