The Ultimate Guide to Chihuahua Heat Cycles: How Long They Last and What to Expect
Chihuahuas, like other female dogs, go into heat, a period of fertility when they are receptive to mating. The heat cycle typically lasts for about 21 days, and it occurs about every six months. During this time, Chihuahuas will experience a variety of hormonal changes that will cause them to become more affectionate and playful and have a swollen vulva and bloody vaginal discharge.
It is important to keep Chihuahuas away from male dogs during their heat cycle to prevent unwanted pregnancy. If you are planning to breed your Chihuahua, it is important to consult with a veterinarian to determine the best time to do so. Breeding outside of the heat cycle can lead to health problems for both the Chihuahua and her puppies.
