It is important to know when a Yorkshire terrier is ready to breed, especially if you are thinking of breeding it. The Yorkie is a small breed and is usually around seven inches tall. They were initially bred to catch rodents in mine shafts. The dog usually comes in heat in six month cycles and the first one is seen when the dog is six to 18 months old. For small breeds such as the Yorkshire terrier, the first heat comes sooner.

What To Do When Your Yorkie Is In Heat, and How Long Are Yorkies Pregnant?

A Yorkie becomes sexually mature during six to 18 months old. During this period the female dog comes into heat. Male Yorkie usually start producing sperm during their sixth month. At this age, the dogs are not yet socially mature and they can’t find a mate until they reach the age of two. There are three parts of the heat cycle.

These are proestrus, estrus, and dietrus.

  • Proestrus is the first phase and often indicated by the swelling of the vulva as well as the bloody discharge from the vagina. The female will not want to mate with any male. The phase can last up to around nine days.
  • Estrus is the second phase of the heat cycle. The discharge from the vagina becomes lighter in color and a reduced amount. During this phase, the vulva swells more compared to the first phase. The female will now entertain male dogs. The phase can last between three and eleven days. The veterinarian can perform a vaginal smear to determine whether it is the right time to breed the dog.
  • Diestrus is the last phase of the heat cycle. It starts as soon as the second phase ends. The vulva starts to decrease in size and the discharge becomes redder. If the Yorkie is not pregnant, the last phase lasts from 60 to 90 days. If the dog is pregnant, then the phase continues until the dog gives birth.

Physical Signs of Yorkie Heat Cycle

When your Yorkie is in heat, it means she’s in a period where her body is changing to accommodate mating with a male dog. For this reason, you’ll notice just a few physical changes that can indicate the Yorkie heat cycle.

For one thing, you may notice that the vulva is swollen in appearance. Sometimes, it may even become darker than usual in terms of color. In terms of menstrual discharge, it’s completely natural during the Yorkie heat cycle. Typically, any discharge should be within the color range of red to light pink. 

Changes in Behavior

Behavioral changes might be easy to spot if you’re able to monitor your pup. She might start gathering her toys and nesting them near her, an instinct caused by increased hormone production. Or, you might notice a change in her appetite because of the hormones, which could mean she eats less or more. 

If you notice mood changes, this is completely normal in the Yorkie heat cycle. Try to make sure that she’s extra comfortable at all times and isn’t experiencing separation anxiety during the heat.

When you have a Yorkie in heat, you’ll want to know a few things that could help you best take care of her needs during this time. 

First things first, it might be a good idea to keep potential male mates out of her vicinity for the first heat stages, since they sense her pheromones early on. Initially, Yorkies, including Teacup Yorkies, in heat might act aggressively towards male dogs, as they won’t be receptive to them until later on in the cycle.

If you don’t want her to mate, she should avoid all males during this period. 

Try to keep her in a contained area for this period and off any furniture or rugs you wouldn’t want to remove stains from. You could even use disposable diapers for her comfort and easy cleaning.

As general cleaning goes, you can give her regular baths or purchase gentle canine wipes to remove any remaining discharge that might adhere to her coat.
