We are not breeders but just a private family who rescue and foster dogs. The mother of the puppies is a !00% Chihuahua and the father is Chihuahua/ Jack Russell. So they are 75% Chihuahua and 25% Jack Russell. Our mama Chihuahua had to have a C-Section...but thankfully everything went pretty well....;-) You can come to our home and visit your puppy as often as you like.
