Is my 5 1/2 month old GSD in heat?
I've noticed this past week that my intact male beagle has been trying to mount her more & more. When I looked at my GSD's vuvla, it looked a little swollen but I've never owned a female dog so I wasn't sure. I haven't noticed any bleeding & there was so signs of blood near her vulva. I took her to the vet yesterday bc I have her scheduled to get spayed next month. The vet said it looked more like a yeast infection but wasn't sure if it's from her vulva being swollen from going into heat or what. I left kind of confused. I'm paranoid my beagle is going to get my girl pregnant before she gets spayed! So I guess my question is, how do I know for sure she's in heat??
