Sunny went into heat 2 weeks ago. Up until yesterday, she was still bleeding although it had certainly slowed down. We thought she was done as of yesterday. She has been having more frequent urination the past 24 hours and actually woke us up at 3am to go out (first time ever). This morning, I took her for her walk and she marked her usual 5-6 times. Then she did 2 more and they were both pure blood. I am concerned she may have an infection or is this normal? As I said, I have a call into the vet but was wondering what you guys think...

Thanks.
