Oh Robin I can understand why you are having trouble with this decision. Charlie is one adorable little (BIG ) guy! I just can't allow myself to be anywhere near puppies because I know how weak I am. I don't think a third dog would work for us because Bella and Ripley have such a bond at this point. I don't know how Ripley, more than Bella, would feel about adding another dog. Like you said, though, there are lots of people who have three, four and more dogs and handle it beautifully. Good for you taking the time to weigh the pros and cons. Good luck in whatever you decide. Any pup that winds up in your home sure is lucky that's for sure!
