Ultrasound has puppies, X-ray showed nothing, done at the end of week 8!

My dog got an ultrasound and X-ray same day back to back at the end of week 8, ultrasound was first done then X-ray couple mins later. On ultrasound the vet saw puppies with heartbeat, but X-ray showed no puppy. The vet doesn't have explanation for this and we are very worried. All signs the dog is having make us think she is pregnant, appreciate any advise!

@chiamoni Ultrasound can detect pups as early as 22 days and will typically detect in the 22-28 day range. X-rays don’t detect until day 42 or so, with 45 being more reliable. Pups could just be younger than you think they are.

@oldwoodsman The X ray was done at the end of 8 weeks which is over 56 days… That’s why it’s confusing…

 

[oldwoodsman]

@chiamoni My point is that the puppies may be less than 8 weeks,

 

[chiamoni]

@oldwoodsman Right, that could be a possibility…
Just worried if something is wrong such as the puppies can only develop heartbeat but not bones, like the development stopped…?

@chiamoni Did you do progesterone testing for that day count or no?

 

[chiamoni]

@dukedesu No, we didn’t…

 

[dukedesu]

@chiamoni You could be as much as 7 days off for a live breeding.

@chiamoni If the dog had recently eaten, few hours, they have more trouble seeing the spines, feet, hands. Maybe your dog had eaten recently. Also they should have an explanation lol!

@chiamoni It’s best to x-ray around day 55-ish. It might have been too early, does the UC still show pups?

 

[chiamoni]

@maddox The X ray and ultrasound both done at the end of 8 weeks so over 56 days, ultrasound showing puppies and heartbeat, nothing on X ray.

@chiamoni Did you guys progesterone test? Do you have when she ovulated

 

[chiamoni]

@maddox No we didn’t do progesterone test…

@chiamoni Then you don’t know if they’re even old enough for the bones to be calcified enough to be seen via x-ray
