Please, unless your dogs are excellant examples of the breed and have many traits to pass on and improve the breed, reconsider breeding until you have done some more research and are more knowledgeable on the subject. [/B]
I agree with this 110%... If your female is that much shorter then she probably is not within the standard, and therefore should not really be bred. Breeding is to improve a breed, and when people get a purebred puppy they expect it to look like the breed. Are your dogs AKC registered? Do they come from good (ie. champion) lines? Are they show quality? These are all questions to ask before breeding.

You are going to find that most on here do not condone breeding unless you are a reputable and established breeder already. there have already been several good points made by other posters, so I sincerely hope you really think about this before jumping into the responsibility of breeding.
