AVA is my 8 month old GSD. She had her first heat cycle starting on May 1st (7 months of age) of this year, bled for 3 weeks, had mildly swollen parts. It seemed to be a normal cycle. Now 7 weeks from when she started her first cycle she appears to be having another. Her parts are more swollen than the first time, and from start of swelling to bleeding took 3-4 days. Can this be normal to have 2 cycles so close together? She has not had any contact with any male dogs. Should she be checked by a Vet? Any help will be appreciated.
