There are many symptoms of dogs during menstruation, such as vaginal swelling, loss of appetite, lower body bleeding, bad temper, prone to constipation, decreased resistance and other symptoms. When a dog has its first menstruation, the vagina will be swollen and red fluid will flow out. Taking care of the dog at this time will be very troublesome.

Dogs usually show symptoms such as loss of appetite and discharge from the vulva. When a female dog first starts to go into estrus, there will be a small amount of secretion from the vulva. As the estrus process continues, a small amount of dark red blood will appear.

Bitches will also show symptoms such as loss of appetite during estrus, so the dog owner should be mentally prepared. It is recommended that the poop scraper prepare some pet menstrual pants at home and put them on the female dog when she is in heat to prevent the female dog from soiling the house.
