Okay so im not sure which is going on. Im thinking its her starting her cycle, she is 10mo old so this would be the first. To start, her vulva is swollen and red also there seems to be so brown discharge coming from it (i have a towel on the couch and thats the color showing). However my other dog does have vaginitis (currently being treated) and the two play together, so im not sure if she may have picked something up. Normally id go to the vet buuut quite honestly I dont want to pay the emergency fee for them to say shes going into heat. So I figured id ask here first. Thanks
