OK so Ms. Annie started spotting bright red blood yesterday.......and I know I sound ignorant but I have never had a girl dog before. She is ?8-10 yrs old according to the vet. I was going to have her spayed and breast masses removed earlier in the summer but my Mom went in the hospital and the surgery got cancelled. Interestingly enough I think she may have been having a false pregnancy around May-June because soon after into July and August her bewbies shrank down dramatically and the masses disappeared. She seems to be acting OK, eating OK, just licking back there and the spots she is leaving around. I haven't checked her temperature. Do you think it is "just" heat or I should I worry about pyometra? She was adopted from a shelter a few hours away and appears to have had many litters......
