Dogs generally come how many days before the end of menstruation

The end of a dog’s period is usually 7 to 14 days, with most dogs coming into heat for the first time at 8 to 10 months, possibly later for large dogs and earlier for small dogs. Sexually mature dogs come into heat twice a year, mostly once in the first half of the year from March to May and once in the second half of the year from September to November. Dogs in heat have many symptoms, the most common of which are engorgement of the genital tract, enlargement and bleeding discharge. In addition to this, there are signs of excitement and loss of appetite. When a female dog is found to have a bloody discharge from her reproductive tract, it is important to identify whether it is a normal estrus or a problem with the urinary system.
