There is no central registration for the Service Dogs or Guide Dogs in the USA.
Based on the number of dogs trained each year and the number of Active Dogs published from each of the schools it's estimated there are between 8,000-20,000 active GUIDE DOGS for the blind in everyday usage. And between 15,000 and 25,000 other Service Dogs in use.
Guide Dogs for the Blind added 343 new dog teams in 2009.
The Seeing Eye Graduated 274 dogs, 74 of which were new dog teams in 2009.
It's estimated that between all the schools in the US, only 1,000 Guide dogs and nearly 2,000 other types of Service Dogs were trained in 2009.

Depends on where you are, but in some US states, it is illegal to refuse a working, certified Guide Dog
Then you get a new guide dog or retrain the old one. Preferrably retrain the old one because it might face what us human's consider the "death penalty".
There are several dozen schools. A list is here: http://www.gdui.org/schools.html

There are too many programs and independent trainers to accurately count how many guide dogs are in place in the United States. However, the Seeing Eye, the most recognized program in the world that trains guide dogs has reported in their 2007 annual report that they had 1,760 graduate teams in the field. Note that not all guide dogs are trained by the Seeing Eye. There are many programs that train guide dogs, but only those trained at the Seeing Eye are properly called "Seeing Eye dogs." It is estimated there are about 20,000 Service Dog users in the US. The Seeing Eye graduated 60 new dogs in 2009. Roughly 1,500-2,000 Service dogs graduate each year, about 150-200 of those for the blind.
