I posted this once under other thread and did not receive many response, start and new one here untill confirm...Yes

or No
3/15 was Candy's 44th days after first tie, she has all signs showing that she should be pregnant (ofcourse, not sure). I told her to the vet. and took a xray, doc said he could not see any skeleton, but he said he can feel like she is pregnant. I am confused...
Well, he said may be she did not conceive at the first tie and still too so to show in Xray, he want me to bring her back for another xray after 10 days and he is not going to charge me for the xray.
Any of you have the same situation? How soon can puppies show via xray?
Here are some images... what do you think..?
