How old does a dog have to be to breed?

We have 2 Alaskan Malamutes, Neo who is 1 year in 2 weeks and our recent one Meesha whom we got in January and is 5 months. We want to breed them to help there breed which is rarely seen around where we live and because....well we just want to help it, not just for fun and make money and that crap. My mum said that we are going to breed them when Meesha turns 1 in November this year I just want to know if a dog her breed or size (they are big dogs) is able to have puppies at the age of 1? She's even put Neo up for stud when he was 10 months and she was told that he was to young (which in all honesty he kind of is/was). I just wanted to clear something up to people who aswered negatively and horribly to this question last time, I have told my mum that Meesha (especially her because she is the one who has to carry them and give birth) and Neo are to young but she just says that she'll be fine. They are also KC registered and have been checked for any problems and they are in the clear. Would one and half be ok? My mum has thought about getting Neo neutered but then she thought about breeding him to help the breed, hense buying Meesha (and to keep him company).
