Chow chows have a risk in being anesthetized due to the short muzzle. Veterinarians should be aware of this potential problem. Excessive tearing may mean your Chow has entropion, a condition in which the eyelids turn inward. Heat prostration occurs in Chows with high humidity and temperatures above 80 degrees. Do not leave this breed of dog in a hot or closed in area, especially in the sun.
Chows are strong willed and stubborn.
Socialization should begin at birth. Continual training is necessary to ensure a well-trained dog. Chows can be aggressive with other dogs and people, and may bite the owner if touched unexpectedly. They are especially touchy in hot weather. Because of their strength and often aggressive nature, be very careful of this breed with children.
