Hi everyone and thanks for answering my questions so thoroughly. Have made decision to fence in my yard instead of going with invisible fence and have looked into having a dog sitter come to house once every day during week. Hopefully fence will be up by early spring, I have a couple of breeders in the Pennsylvania area in mind. I am still a little confused though about EVENTUALLY being able to leave dog at home during week by itself. Does anybody do this regularly? There must be Vizsla owners who go to work, right? Thanks again, John.
