Dogs/Number. of puppies shown in Ultrasound and x-ray are different


Hi, my female spitz ( the small variety ) comes into heat every 4 months…. We bred her during the last 2 heat cycles, but she did not conceive …. This time we mated her on December 3rd and December 4th 2012 with one male spitz ( slightly bigger than her ) and on Dec 6th with another male spitz ( which is only half her size )…. We took her for Ultra Sound on January 19th ( 48th day since the first mating ) and the vet said that she could see 2 puppies on 1 side and 1 puppy on the other side …. She asked us to come again the following week for an x-ray to determine the accurate number of puppies … Today, January 28th ( 57th day since the first mating ), I took her for x-ray and the vet is telling that she can see only 1 LARGE puppy ???
1)Is this possible ??  If so, how  ???

2)Is x-ray the absolute diagnosis for determining the number of puppies ???

She has been vaccinated completely ….


Hi Sujatha,

Doctors and x-rays aren't infallible. Depending on their position, a puppy can be unseen by x-ray. So, yes, it's possible that she could be carrying more than one puppy. You really won't have absolute answers until the puppies are born.

Good luck with the litter!

To date, I've owned 7 dogs, all of which have lived into old age. Having cared for them in all stages of life, I feel I can offer sound advice to other pet owners, and people considering getting a dog. I am knowledgeable about the AKC (American Kennel Club) dog breeds, training and exercise, caring for sick and elderly pets, feeding, as well as many holistic treatments pets can benefit from. My only request is that you write me using standard English and punctuation.


My life experience in this field is more like "on the job training" rather than an actual degree in animal welfare. You may benefit from my experiences over the past 30 years. Aside from the dogs I've owned, I'm also involved in "breed rescue" and have fostered several dogs, all of which have been adopted to wonderful "forever homes". I find helping people who want a dog very rewarding.

Real life experience, based on over 30 years of dog ownership.
