You're gonna love this breed, I've been onwing them since 1979, I've had four now through the years.
My current girl has just been bred and should be delivering pups in late July or early August.
Is your dog from a local breeder or is it being shipped in from somewhere?
You should be able to find info regarding vizsla clubs on the net, I've found a lot of information from it.
I wish you the best with your new hunting/family companion. They really love to be with the family and you, will become protective and absolutely loving dogs. Great hunters to boot!
