I am glad that you have decided on a dog. Do you now feel emotionally stable enough to look after a dog. I am referring back to your first post. Do you live in a place that has out doors for a dog to be? A friend of mine adopted two different puppies many month apart. She tried this twice but and had to give each dog up. She basically has no back yard. It is a big thing for you to commit to.
If you think that you can do this then kudos to you and I wish you well in your quest to find a Vizslar.
