Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 30 lbs
We just had our dog Ladybug spayed on Tuesday. We started to notice huge deep red bruises developing around the mammary area after the first couple of days, and now that bruising has spread down her thighs. They said her bloodwork was fine, and her gums looked good. Bathroom breaks normal, behavior perky, seemingly normal, with sparatic lethargy. Pain pills are working. What are these bruises, and what may have caused them during surgery?

These bruises happen when blood seeps into the tissue surrounding the surgical site. This usually happens when a dog has a coagulation disorder, or the dog bled a lot during the surgery (for example when spayed during her heat) and then the blood cannot be absorbed quickly enough and seeps into the tissue. If the bruises expand more and should your dog develop white gums or pale gums, then she needs to be seen by your vet who should do a packed cell volume blood test and a coagulation panel. Dogs can easily bleed to death when there is a coagulation problem or continuous bleeding.
