I'm considering buying a male puppy. I have a seven-year old female yorkie that I adopted from a puppy mill rescue. I also have a Westie that I bought as a puppy. I love both breeds. My nephew has a six month old female AKC Yorkie and I would love to provide a male for him because he does plan to breed. I have a few questions first. I've always had female pets. No particular reason, it just worked out that way. Are males harder to train, housebreak etc? I will probably have him neutered after he produces one liter. My nephew's female is AKC so I assume I should buy an AKC rather than CKC right? Anything else I should look for or be made aware of that would help me in my process. The male I'm thinking about buying weighs 15 ounces and he's five weeks. Also, how old should a male be before I use him to breed?
