I only have two Yorkies, and could afford more but I would have think about how much more difficult it would be to take them places. Right now Zada and Azrael go everywhere with me, except to Dr. dentist, Wal-Mart and such. I put them in the bike basket and off we go, I take them for daily walks, weather permitting, they go to play-dates, travel with us and on and on. If I had more than two, it just wouldn't work very well and I would have to leave them home more often I suppose. Soooooo..........just think about things very carefully before considering a fifth dog. Bentley is a beautiful boy and your so lucky you have him. So very many people are still looking for a baby like him and some can't even afford even one dog. Count the blessings that you already have.
