congats on the new baby (both). I can understand your concern about leaving your furbaby alone for such a long period of time. You might contact your vet and ask about recommendations for boarding your yorkie...you will also need the paperwork from the vet that says everything including Bordetella is up to date. Please be careful if your dog isn't up to date on all vaccines as Parvo and bordetella (kennel cough) is very contagious and they don't actually have to be near the other dog to catch them...bordetella is airborne and parvo can live on surfaces for many months unless bleached (or similar disinfectant).
too bad you don't live near one of us (lol) we here at yorkietalk would make excellent puppysitters!.
