From my column on dogs, Cosmo and rush to dope up our hounds:

You may have heard that Eli Lilly, the maker of Prozac, has just launched Reconcile, a chewable, beef-flavored antidepressant. It’s designed to lessen separation anxiety for dogs left alone for long periods of time. “A lot of people who have this problem with their pets will come home to a trashed house,” a Lilly spokesman told the Associated Press.
I’m sympathetic to better living through chemistry, but isn’t there something shameful to this?
Dogs are pack animals. The romance of lone wolves notwithstanding, most canines don’t want to be alone. Cosmo is spoiled in this regard. My wife and I work from home, and he’s rarely left alone for extended periods of time. (And when he is, he tends to surf the web using my credit cards. Need an extra metric ton of tennis balls, only slightly chewed?).
As a general rule, if you find that your normal dog needs to be put on antidepressants just to get through the day, maybe you shouldn’t have a dog. Or, perhaps you shouldn’t have a breed that can’t tolerate long periods of inactive isolation.
