I went with my sister to look at chihuahua puppies and they had an adult for sale "because she wouldn't get pregnant". I ended up taking her because this wasn't the nicest place and I figured I could have her vetted, spayed, and place her in a new home (i'm experienced in rescue). That was about 2 weeks ago - she is now obviously pregnant, probably about 7 weeks or so. She is going in for an xray on Monday to find out how many and to find out if she'll need a c-section or not. She is about 4 1/2lbs and the male that was on the property was about the same weight but with a larger head. I'm just looking for some tips, suggestions, warnings, etc. I'm experienced in whelping large breeds so I know the basics, I would just like to learn more about the specifics of whelping chihuahuas. Returning to the breeder is NOT an option.
