Most of you know what happened to maddie about a month ago--well a couple hours ago i was rubbing maddies tummy looking at her nasty scar they left when they tried to spay her AGAIN

--and then all the sudden my fingers were wet??? i looked down and ALOT of yellow pus (sorry) was comming out of the end of her scar--i rush her to the other vet, and they said it maybe a reaction to the internal stitches, and gave me a stronger antibiotic for the next 10 days-----i dont understand this, maddie was on meds after the surgery screw up and her tummy was kept clean and looked good except for a larger nasty scar, and she been acting just fine. also she never had a reaction to the first spay the rescue did right b4 i adopted her???? i glad i caught it---but i dont understand this infection---and now that im thinking about it-do you think theres a chance it might have spread to her internal organs??? again shes acting like nothings wrong--but im so worried about her. and why did this become infected???
