I'm sorry that it didn't work out. We have a 4 month old male and have thought about getting another to keep him company, but it scares us thinking that it might not work out. I agree, maybe letting your puppy mingle with the possibley new addition to see how the react with each other, I know that that's probably not always going to be easy to do, but whoever owns the puppy hopefully will let you see if they bond. Good luck maybe Sophie will find a another new brother or sister that works.
