Find a new vet.
Of course the vet wouldn't comment...I wouldn't want to admit that I was employing someone giving that kind of info to my patients either.
Actually, human pregnancy test are designed to detect FEMALE, as in HUMAN hormones released when pregnant, that are carried in urine. (Duh, peeing on a stick...)
If I'm not mistaken, canine pregnancy hormones are carried in the blood, not the urine?
Anyone know for sure off the top of their head?
