I have owned two Hungarian Vizsla
s and I can say that they are one of the most demonstrably affectionate dogs you are likely to come across, and as a result have earned the title of the Velcro Dog. They love being close to their owners at all times, but will also 'work away' as an HPR. They are extremely intelligent, and pick up training like a sponge, they have a lot of energy, and need a lot of exercise or will often become bored and destructive (I am told that digging can be a problem) mine gets good walks/runs twice a day, off lead, and is a fantastic dog.
They do not take well to harsh handling, and can have a tendancy toward resource guarding if not handled correctly.
The book 'The Hungarian Vizsla' by Gay Gottlieb is invaluable, in my opinion, if you are looking to research the breed properly.
It can be ordered from here:http://www.russetmantle.co.uk/
(The book also contains a chapter on the Wirehaired Vizsla)
Here's some of my Vizsla history, it may go on a bit, but stick with it if you choose to:
My first was a Smooth haired Vizsla, which we took on as a rescue dog, unfortunately he had some pretty serious agression problems, and with two small children in the house, and no risk worth taking in that situation, he was returned. We don't know that much about his previous history, but he had been to a previous home who had experienced problems between him and their other dog, he had developed some serious Resource Guarding issues, which he showed on several occasions toward my wife and I, and on his last day with us, resulted in me almost receiving a bite to my left thigh, I escaped with ripped jeans and a racing heart. He was only six months old, and apart from me picking up a tomato off the floor, was completely unprovoked... My son, who was three at the time would have picked that up, and the attack would have been face height... It didn't bare thinking about...
That aside, I did a lot of research into the breed, both prior to and after that dog, and it did not put me off the breed, most breeders and owners were shocked to hear that a Vizsla would have reacted like that, let alone one so young. After some further research it would appear that he may have been mistreated, or had picked up some bad habits in his previous home, but I will never know for sure.
Six months later, I picked up an eight week old, Wirehaired Vizsla, (who still looks like a smooth - they don't all get the wirehair), and he is now just over 9 months old, he is a fantastic dog. He has integrated fantastically well into the household, and is virtually my son's best mate, he is extremely affectionate toward the family, will bark and growl like a loony if he hears or sees something he thinks I/we need to know about, and is extremely easy to train. I have owned a few dogs in my life all of which have been gundogs and I am officially smitten with Vizslas.
I know several other owners and breeders who work them and find them extremely versatile in their abilities...
If you are able to spend the time with the dog, give it the exercise it will both need and crave, and provide the affection it will almost undoubtedly command, I honestly don't believe that you will regret owning a Vizsla.
The breeder I got mine from currently has a couple of litters, (born in June) http://www.ragnolds.com/
(one litter smooth, one litter wirehaired) and is only a couple of miles from me, if I am able to be of any further assistance, or with any further advice, please feel free to get in contact.
Best of Luck!
