Tila was spayed almost 3 weeks ago now and yesturday i noticed a lumpy bit at the top of the wound. Today it's all red but with a blue / black bit in the middle? She went to the vet about a week ago and they siad she was happy with it and was healing well so is it just some late swelling and bruising or something i need to be worried about? photobucklet taking ages to upload but there will be pic's to see.
