How often do dogs have periods?
Most dogs come into heat twice per year, or about every six months, although the interval can vary between breeds and from dog to dog. Small breed dogs may cycle three times per year, while giant breed dogs may only cycle once every 12 months.
Dogs generally go into heat twice per year, every 6 months. However, like with humans this can vary dog to dog & breed to breed.
