Vizslas are great. I work with one named Harcos, and he's one of the sweetest dogs I've ever met.
When you're thinking about buying or adopting a Vizsla, please remember that originally, all dogs were bred for a specific purpose. They all had jobs. Vizslas are hunting dogs. This is one of the oldest pointing breeds, so expect very high energy, keen intelligence and alertness, and lightning-quick response. That being said, they were bred to locate game, not kill it, so their temperament around other animals is virtually non-aggressive.
They're very pack oriented, and food driven. They're also very tactile. They love to be touched. If you have more than one Vizsla, most likely they'll be piled up on top of each other sleeping. If you have only one, most likely they'll be piled on top of you sleeping.
There are some health considerations for Vizslas. Overall, they're very sturdy, but once in a while, things do go wrong. Here we go:
Super high energy - Mental health counts. If you come home from work after having left your Vizsla for eight hours with no mental activity, a.) do not be surprised to find something chewed, and b.) don't get mad at the dog when you find something chewed. You can't take a dog bred for hunting since the 9th century and expect it to suddenly develop inertia for your convenience. If you can't take your Vizsla out for a solid hour of vigorous outdoor fun at least once a day, every day, hire a pet sitter willing to do that for you, or be kind enough to own a breed with less energy.
Epilepsy - Vizsla's do have a higher rate of epilepsy than some other dogs, so be mindful. I'm not saying wait around for a thrashing grand mal seizure, but I do recommend that you take your dog to the vet if you notice any of the following symptoms: a spaced out look; dialated pupils; an unusual stop in walking which starts up again in a few seconds, etc. Things that seem as though your dog is spacing out. These symptoms can signal petit mal seizures. Vizslas are so sharp and alert, weird little glitchy, absentminded-looking behaviors like that need to be checked out by a professional.
Hemangiosarcoma and Lymphoma: Vizslas also have a higher instance of these two cancers than some other breeds. Again, because of the Vizsla's steadily energetic, alert, and food-driven nature, the lethargy, weakness, and appetite loss associated with these cancers is easy to spot.
Hip dysplasia: This isn't as much of an issue as it used to be since breeders have become more mindful over the past decade or so. Do keep in mind, though, that these dogs are fine-boned, and they're not built to withstand too much weight gain. Be loving to your Viszla, and maintain a healthy weight for your dog to avoid joint problems.
For the right home, and with humans who also love an active lifestyle, these dogs are fabulous. I highly recommend Viszlas as high-energy four-legged family members!
