Wow, how ignorant can a person be to NOT spay? All mine were spayed/neutered by 7 months old, and the two the were 7 months old when fixed, I felt awful thinking I'd waited too long. I always want to grab people by the collar when I see them out with their unneutered male dogs and scream "Neuter him! For the love of your dog, neuter him!"

Gee.... I'm with Jan on this one... its so much fun to save the lives of unwanted pets.
