Dog with infection??

Ha

My dog is about 6 years and is a cavalier king charles spaniel.

Lately she pees sooo much. she goes out all the time and pees about 3-4 times every time. it doesn’t seem like she’s in pain when she pees though. She also has become veryyy smelly even after being bathed. we also thought she was in heat but she leaves little pools of like diluted blood around the house.

any ideas?!!!
