My Chihuahua is pregnant with...

Question
My Chihuahua is pregnant with her first litter. Her mate is also
Chihuahua. She is extremely petite and I am afraid that when the time
comes, I will not know what to do. Her due date is approaching (even
though I don't remember the exact date, I know it was in the 20-something
of February)....can you advise on anything?  

Answer
Pregnancy lasts 63 days plus or minus 5 days.  You can monitor rectal temperature...when the temperature drops below 100 degrees, she should whelp within 24 hours.  If she is in active labor and not passing a pup in 30-45 minutes, you need to call the vet.  Often times Chihuahuas will need C-sections, so be prepared for a $300-500 vet bill.  Also, Chihuahuas tend to become hypocalcemic so make sure she is eating puppy food for the extra calcium.
