So I have a 9 year old adopted mutt that I've had for 7 years. Recently, I've been thinking of bringing a puppy home as a companion for her. She loves large boy dogs, but is indifferent with girl dogs. Not aggressive by any means, but shows no interest. The puppy is a 14wk old male Cane Corso. They met tonight at the breeders, and as I figured, she really wanted nothing to do with him. I've heard most people say that it's normal for them to be like that for a while when a second dog is added, and then they eventually warm up and become inseparable. I know each dog is different, but what was your experience bringing a second dog into the mix? How did it work out for you? Here's a pic of the little chunker.
