Are there any other factors you are taking into account in your decision to Breed you female? No she's not too old and no the male isn't too young, but
are you considering anything else like Pedigree/Bloodline, faults/recessive genes that you should breed out? Height and weights of both the male and your female? I am amazed at your non-chalant attitude towards Breeding, as if it's that easy? I'm not trying to insult you but there are a lot of other things to think about than just her age. Realistically there are a lot of people who have this Breed and love their Dogs, but I don't believe every dog should be bred just based on your love of them. There's a Breed Standard, there's confirmation; straight back, straight teeth, small ears, weight in proportion to height? It takes a lot of research etc. Money and experience, not to mention the time and effort!
Let me get off my soap box now. I've said enough, it's a sore issue with me since I have seen so many dogs poorly bred.
