Are Vizslas Hypoallergenic? No. Although, vizslas have minimal shedding. This is because of the fact that they only have one coat of fur. Most dogs have a longer topcoat and a shorter bottom layer. Vizslas only have the bottom layer. Allergens from dogs usually live in the thicker second coat, therefore without that coat, vizslas naturally have fewer allergens. They do still carry those allergens, but with proper grooming, they become very minimal. Therefore if you keep up with cleaning then their shedding is manageable. If you keep up on grooming they are less likely to cause reactions in people with allergies. You should know that if they shed people will be more susceptible to allergies. Because of their minimal shedding, there are some people who consider them to be hypoallergenic. We absolutely love this breed but, we would not recommend people who have extreme canine allergies to buy a vizsla.
