Been a week since tinkys spay now and I noticed on firday night she was swollen by her back teats and they were sore ect. I put this down to the op and it was all part of the healing process as her cut was fine ect. Last night her teats had gone rock hard. So this morning we have been to the vets and she has mastitis I feel awfull that I didnt take her sooner can anyoe advice how long this normally takes to clear up? She has been perscribed antibiotics and has to go back for stiches out on thursday.
