Yes, teacup yorkies are classified as hypoallergenic. First, they have hair instead of fur, naturally producing fewer allergens. Second, teacup yorkies don’t have the same hair growth and shedding cycles as other dogs. As a result, teacup yorkies hardly shed.
Moreover, the hair they shed usually falls back into their coat, so they’re less likely to trigger an allergic reaction.
However, no dog breeds are truly hypoallergenic, and teacup yorkies are not allergy-proof. In some rare cases, they may still cause an allergic reaction. The probability of this happening can be reduced with regular maintenance.
Make sure to groom them regularly; daily brushing and regular trims and monthly trims will do wonders.
