A 2018 review published by the National Institutes of Health found that 10 to 20% of the world's population is allergic to cats or dogs.
Allergy to dogs is a reaction of the body to certain proteins contained in the secrets of the animal's skin glands and its saliva - wool itself does not cause allergies.
In fact, allergies occur in response to allergens that are secreted by the sebaceous glands and dead skin cells of animals (dandruff).
These allergens are also found in the saliva and urine of dogs.
Doctors may advise their patients with pet allergies to give up the dog.
Hypoallergenic, as a rule, are such breeds that minimize the risk of allergies.
Allergies in humans do not occur on hair fibers, but on proteins that are in saliva or dog hair.
There are different ones among them - from tiny Yorkies to medium-sized Candiaguas, and you are sure to find a pet that will appeal to you.
