One thing I hate is when people get angry that someone "hasn't done their research" -- when that is clearly what this person is doing. It's those that critisize questions that make people do stupid things because they are afraid to ask. If she hadn't asked, and let her male with the puppies and he killed one? THEN everyone would be angry that she HADN'T asked!
I'm new to breeding and I still have alot to learn, too, okpik. My female had her first litter three months ago. I didn't know about males near the litter either. My puppy was out and about since day one, and my co-breeder allowed each of the dogs near him. Her male was the only one who came near. She told me that most dogs are afraid of young puppies, but that most males act aggressivly towards them, so that he was unusual. He would sit with the puppy between his legs, sniffing him and licking him, and nibbling him. All of the females were quite careful around him. Isis loves puppies but she didn't get too near, and Jag was plain terrified of him
