How Often Do Yorkies Go Into Heat?

Yorkshire Terriers typically go into heat about every 5 to 8 months, which means most Yorkies have two heat cycles per year. Some may cycle as often as every 4 months while others go closer to 9 months between cycles. The timing varies from dog to dog and tends to become more regular as your Yorkie matures.

Young Yorkies often have irregular cycles during their first year or two. It is completely normal for the spacing to be unpredictable at first. As your dog’s hormones stabilize, usually by age 2 or 3, the cycle becomes more consistent and easier to predict.

When Does a Yorkie’s First Heat Happen?

Most Yorkies experience their first heat cycle between 6 and 10 months of age. Because they are a small breed, Yorkies tend to mature earlier than larger dogs. Some can go into heat as young as 4 or 5 months, which catches many owners by surprise.

The first heat is often lighter and shorter than subsequent cycles. You might barely notice it. Pay attention to subtle signs like slight swelling of the vulva, small spots of blood, and behavioral changes as your puppy approaches the 6 month mark.

How Long Does a Yorkie’s Heat Last?

A typical heat cycle in Yorkies lasts about 2 to 3 weeks, though it can range from 10 days to a full month. The cycle has four stages, each with different characteristics.

Proestrus lasts about 7 to 10 days. You will notice vulvar swelling and bloody discharge. Your Yorkie may be more clingy or restless during this time. She will attract male dogs but will not be receptive to mating yet.

Estrus is the fertile phase and lasts about 5 to 10 days. The discharge lightens in color and becomes pinkish or straw colored. This is when your Yorkie can become pregnant, so extra caution is needed.

Diestrus lasts about 60 to 90 days as the body either supports a pregnancy or returns to normal. Anestrus is the resting phase between cycles when the reproductive system is inactive.

Signs Your Yorkie Is in Heat

The most obvious sign is a bloody discharge from the vulva, along with noticeable swelling. Because Yorkies are so small, the amount of blood may be minimal. Some owners barely notice it because their dog keeps herself very clean.

Behavioral changes are often easier to spot. Your Yorkie may become more clingy, restless, or anxious. Increased urination is common as your dog marks to advertise her status. Some Yorkies lose their appetite temporarily, while others become more demanding of attention and want to be held more often.

You may also notice male dogs in the area becoming very interested in your Yorkie. Even if you do not see the discharge, the behavior of nearby males can tip you off that your dog is in heat.

Managing Your Yorkie During Heat

Keep your Yorkie on a leash at all times when outside, even in a fenced yard. Determined males can jump fences, dig under them, or find other ways to reach a female in heat. With Yorkies being so small, an encounter with a larger male could be dangerous for both mating and pregnancy reasons.

Dog diapers made for small breeds help manage the discharge and keep your furniture and floors clean. Many Yorkies tolerate diapers well, especially if introduced gradually. Put down old towels on your dog’s favorite resting spots as an extra precaution.

Avoid dog parks, doggy daycare, and boarding facilities during the entire heat cycle. Give your Yorkie extra love and patience because hormonal changes can make her uncomfortable and moody.

Should You Spay Your Yorkie?

If you are not planning to breed your Yorkie, spaying eliminates heat cycles entirely and offers significant health benefits. Spayed dogs cannot develop pyometra, a life threatening uterine infection, and spaying before the second heat greatly reduces the risk of mammary tumors.

Most veterinarians recommend spaying Yorkies between 6 and 12 months of age. Discuss the best timing with your vet based on your individual dog’s health and development. Yorkies do not go through menopause, so without spaying, they will continue having heat cycles well into their senior years.
