I would presume that there might be more success in finding birds, but I myself would be concerned about safety & being able to control more than one dog at a time.

I have hunted with multiple dogs in my past - quite the riot! Usually lots of action. I think more the point is the ratio of the number of guns to the number of dogs. We try to keep the ratio between 1 dog for every 3 hunters (ideal), and 1 dog for every 5 hunters (a little heavy). That way, we can back each other up whichever way the bird flies, and mix in short, and long-range guns (i.e., IC vs. Full chokes).

Another way to look at it is duration of hunt.  A good dog rotation is almost a necessity depending on the expected duration of the hunt (i.e, all-day vs. 2 - 3 hours), and the drive of the dogs involved.  Most of my hunts are half-day, and Sadie has enough drive to find birds throughout the day.  I wouldn't expect her to last through an all-day hunt, though (although she probably would give it a great go if given the opportunity!)

Most of my multiple-dog hunts now are with different types of dogs (i.e., a lab and a pointer). That way we can take advantage of the in-bred characteristics of the breeds - retrieving with the labs, and hard-working GSPs! The dogs seem to benefit from each other as well, and the GSPs retrieve harder with the lab competition in the field, while the Labs cut their range with the Pointers.
