First of all, the workload involved in going from one dog to two isn't that great a leap.
Second, dogs are pack animals and do well when they have a family (including you) - another dog will be a great source of comfort and friendship for your first dog.
Third, in my personal experience, my first dog was WAY happier once he had a buddy.
However, the dribbling and drooling is just a phase rather than a way of life, and eventually, once you regress back to your dribbling and drooling stage again later in life, then have to come and look after you.
we got a second dog as a buddy for our first guy, it really helped with some behavior problems. watch out though, we now have four!
whatever you do, don't buy the pup from a pet store. many of their suppliers run sub-par operations--elevating your chances of buying a dog from a bad gene pool.
also, the pet store dogs are probably more expensive than a dog from a reputable breeder. there is probably a waiting list though.
another option would be to rescue a dog from a shelter.
