I’ve had many dogs. They were all good with kids, particularly my German Shepherd. Don’t worry about Vizslas, as with everything, it’s you guys (the owners) that will determine the dog’s success in a family environment.
My Vizsla/Lab mix isn’t neurotic with me, but definitely always has a need to be with me. I try to enjoy it, considering I had to put my yellow Lab down almost 2 years ago and that broke my soul to carry him to the car, drive to the vet, and hold his paw while his life ended. I learned from that experience that if my dog wants my attention, I will give it to him/her for a few minutes instead of pushing them away like I did too often (on reflection) with my yellow Lab.
