16 Jan 2020. Around 2 months ago, I removed a large mammary tumour and many small ones nearby. I advised spaying one month after this surgery as spayed dogs (when spayed young) seldom get mammary tumours. This dog is not young, but it is best to spay her to remove the female hormonal influences. The owner came today, 2 months after removal of mammary tumours. But today, the dog's lower body it itchy, inflamed and has pimples or pustules. "I don't advise spaying as the surrounding skin is badly infected and inflamed", I said. "The bacteria may enter the abdomen through spaying. In addition, the reddish brown discharge from the lower private area means that your dog has pyometra (infection of the womb). A course of antibiotics is necessary." Spay is postponed as the skin bacteria from the surrounding area may enter the incision and cause septicaemia and death. Blood work showed normal values. Spay is scheduled on Thursday 30 Jan 2020. After spaying, there will not be any pyometra.
