Just got my dog spayed like 6 days ago due to supposedly Pyometra. After we payed 805 dollars the vet told us there were no signs of it though it still baffled him that she had all the signs. She was in heat in January and went in again this month not even two weeks apart. She was drinking a lot of water too. They couldn't find the bacteria in her Uterus. We took her in yesterday to check her stitches and he said she was fine though she smelled like rotting flesh today we cleaned her up with some good smelling dog shampoo on her back quarter making sure not to get her stitches wet. dried her off and still the smell is there. She leaked some yellow goo like substance please help thanks
