a male chihuahua will mate with a female chihuahua when she is in heat (AKA ovulating, on her period) they can sense it and then have the urge to mate.
I am a breeder and I absolutely love chihuahua's, My best guess is 4-9 years old just because they might have complications(for Male). for the female it is best to weait at least 2-8 years.
Unless he has been neutered he can mate.
My 6 year old chihuahua is pregnant by a 6 month old chihuahua. The vet said that the pups may not survive after birth.

If they are not too old and the female is ready, then they will mate.
About 6 months (for a male) to one year old.

No, but they will "play" mate. Male rabbits can starting mating at about 7 months of age.

If yours is spayed then get a boy they are so much fun,(so are girls) if yours is not spayed then get another girl.unless you want puppies,then get male that's no more than 1lb bigger than your girl.
