How old should a miniature schnauzer be to stud out?

Studding ANY dog should be a very careful choice.People have a misconception that any 2 dogs can make ''great puppies''.The truth is, many dogs carry hidden flaws in their genes that can,when mixed with dogs that may have the same hidden flaws or mutation cause major health and temperment issues. Im not going to get into breeding 'ethics', as this is an age question.

The best age to stud/breed a male mini schnauser sized dog is 16 to 18 MONTHS.The testicles of this sized breed,are fully functional at 8 months of age.Though conception of a female in season can be under 5 months of age,if she is bred to a very virile male or an 'early bloomer'. Younger dogs at like 5-8 months of age, have less mature spermatozoa than older males,say 16 moths old.Mature sperm make better puppies.Underdeveloped sperm have a hard time reaching and fertilizing the eggs,and are not fully able to replicate the DNA within them,as well as the mature sperm.

Also mental maturity at under a year is still developing.An older male,might ''catch on'' quicker than a 5 month old.Some females won't tolerate being a learner bitch,and become frustrated. This can result in ''rejection'' of the male.These rejections can end up in a physical altercation.Males exposed to testosterone,have higher mating drives,that asist in proper copulation.Please note that a bitch can and will attack a male when she is not ready to receive him (bitch will only receive a male in full 'standing' heat).

I hope this helps you out.
