Vizslas are a beautiful and elegant looking breed. But that's the wrong reason to add one to your family. Because they were originally bred to be a hunting companion (i.e. lots of running in the field), they are a very high-energy breed. Vizslas are not your "walk around the neighborhood" kind of dog. If you enjoy the great outdoors and exercising, a Vizsla might be the right match for you. But Vizslas shouldn't be matched to humans based on exercise levels alone. Vizslas are also soft in temperament and love frequent cuddles with their human companions. There is an old Hungarian saying, "If you own a Vizsla, it lives on top of your head." This is a most accurate saying and why Vizslas are often described as "Velcro Vizslas." Be warned, if you bring a Vizsla into your home you may never go to the bathroom alone again!
Vizslas are very high energy dogs and are extremely smart but generally slower to mature. This means you will most likely end up with a puppy until they're closer to 4 years old. But this also means, while Vizslas should be biddable in temperament and therefore very trainable, they may not be the best candidates for those looking to compete at advanced levels with a very young dog. Like a fine wine, Vizslas only get better with age!
And yes, Vizslas shed just as much as other dogs. Its just harder to see because their hair is so short. They don't have an undercoat so that also gives the impression that they don't shed. If you like wearing black you might find yourself eliminating this color choice from your wardrobe as you grow tired of plucking little red hairs from the fabric.
