best time is 3 years. maybe 2. ask the vet.
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.
if the chihuahua is a male
yes, if you want to
NO! If they are both fixed, they CANNOT MATE!
What complications can happen to a female chihuahua when giving birth and during pregnancy!!!
They can mate with other dogs. Now, if you mean in terms of bloodlines and papers, then likely other Chihuahua-Yorkshires.
yes they do cause a chihuahua is a very small dog they can barely give birth to there own i had a Yorkie an a chihuahua mate before you would have to take them to the vet but just make sure to help her out just in case
If its mating companion was a chihuahua then probably yes. However i have heard of rather small dogs mate with dogs much bigger than it.
Only if she conceived, that is, becomes pregnant. As with all other mammals, humans included, the act of mating (sexual intercourse) does not interrupt the menstrual cycle, pregnancy does.
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.
When you combine a Chihuahua and a Chihuahua you get another Chihuahua.
The size dog should be like a Chihuahua 13in and 36centimeters or to be sure another Yorkie just in case
