When a dog has its first period, it will have a swollen and bleeding vagina, hence the name dog’s period. The dog will keep turning around and licking his buttocks, his vagina will be swollen and flushed, and a small amount of red fluid will come out, but not in large amounts. Owners need to wear diapers to prevent their dog’s menstrual blood from staining the floor and sofa. During the period of menstruation, dogs will lose appetite just like humans, so you can give your dog some blood supplements. The dog’s menstruation will come once every six months, but because of the different physique, some dogs physiological period will come more slowly, some to the 1-2 years old first menstruation to come, but generally will still come in 7-8 months for the first time.
