Pregnant yorkie with 2 puppies

Question
Hi Joyce,
I have a 4 year old yorkie normally 4 pounds, now 5. This is her first pregnancy. Her male  yorkie was even smaller then her weighing in about 3 pounds. I just took her to the vet they did blood work an x ray, and they showed me the x ray and they thought it was pyrometra because both of her sides were swollen and her organs being pushed to the middle. So they make me go to an emergency vet and they had an ultra sound machine there. She comes in and says she is pregnant with 2 puppies BUT the puppies are huge, that my dogs stomach is so big it feels like she can give birth now.  I cannot feel anything in her stomach its just swollen & hard. But she is only about 33 days pregnant and it's so early in the pregnancy that on the x ray they can't see the pups because no bones have developed yet. She said her blood work and everything else is fine, she heard 2 pups heart beats. Possibly I will have to do a c section

 My question is: is it possible these are water puppies? Or is it possible she can just have 2 very big puppies? Her attitude is still the same happy just a little more tired. Anyway of knowing if they are water puppies because they are so big already? Will she be able to go through the whole 60 days of pregnancy? I'm giving her vitamins and carrots for a snack and " blue" dog food and just started giving her a little bit of cottage cheese fat free. Thank You!!

Hi Kara

Was the female only bred with the your male?  There was no chance of the neighbors Shi-tzu getting her?   Also, do you know the size of the dogs on both sides of your lines for at least 3 generations?  Just because your male is 3 lbs doesn't mean he doesn't come from a line of giants, or at least some 6 pounders.  

When the litter is small the pups aren't competing for the best placement on the horn, so  they usually are bigger than if you have a litter of half a dozen.  There is always the possibility of a water puppy, however, that isn't common in Yorkies.  Was your female at risk for infection during her season?   An x-ray does not always show the larger size of these puppies, as the weight is mostly fluid. An ultrasound is thought to detect these puppies but it not guaranteed.

When breeding smaller dogs there is always the greater risk of a c-section.  It's a good idea to keep in contact with your vet in case an emergency section is required. Although if they are that large at 33 days a planned section would be better.

Good luck
