  1. I have a 2 year old female Chihuahua about 5 weeks pregnant. I want to know how many puppies she will have, but I can’t afford an ultrasound or the vets.What should I do? She had all her shots and is very healthy. I love my little girl so much and want to do what is best for her, but I don’t have much money. Any advice?

    • Hi Kathleen,
      Chihuahuas often have difficult births and require a c-section, given the bulbous shape of their heads. Your pup definitely needs an x-ray to determine the number and size of pups. The mom and puppies can die during delivery if the puppies are too large to get through the mom’s pelvis. Please seek veterinary care. I hope things go well!
