A Yorkshire terrier in heat demands your special attention. During this stage, your pet yorkie will demonstrate a change in temperament from the usual sweet and adorable pet that you know. Here are some tips on how to take care of a Yorkshire terrier in heat.
• When your pet yorkie is in heat, you need to devote some time with her even for just five or ten minutes. This is the time when your pet Yorkshire terrier would require special care and attention.

• At this time, your pet yorkie will not feel well. She may suffer from vomiting or diarrhea and will feel tired. A yorkie in heat should not be given table food at this stage. Decrease the amount of food and increase water intake. Likewise, her sleeping quarters should be far from other pets, children, or other disturbance.
• Aggressiveness is also one of the primary characteristics of your pet yorkie at this stage, particularly when there is a neutered male dog around. If this sort of behavior persists, you need to call a veterinarian.
• If you do not intend to breed your pet yorkie, consider spraying her once she surpasses the period of heat. You may need to talk to your veterinarian when the best time to do this procedure.
The first heat can take place between 6 to 18 months and is not easily noticeable. After that, your pet yorkie will be in heat two times a year. You should be informed of the necessary precautions and legal and moral responsibilities when taking care of a dog in heat.

You need to place your pet yorkie in a building or proper enclosure to keep her away from male dogs. The only exception is during controlled, deliberate, or permitted breeding. In the absence of proper enclosure, the dog should be directly supervised by a responsible individual so male dogs cannot go near her and breed.
