I think most people will agree that two are better than one, but take your dog's preferences into consideration. I had to get a second dog--Lightning was a wreck when he was home alone. Getting Stomps made all the difference in the world in Lightning's confidence. Stomps was a rescue, and once I'd had him for a little while I realized that he probably would have preferred being an only dog. (However, we're all one big happy family now, so neither I nor Stomps regrets the decision at all.) I think most hounds would prefer a buddy, but before deciding to get a second dog, consider how your current pooch will react.
