Researchers find unspayed dogs live longer

Researchers have found that female dogs that were unspayed or had retained their ovaries for at least six years were more likely to live longer than females that had kept their ovaries intact for a shorter period. As a result, researchers advise dog owners to consult their veterinarian about the pros and cons of keeping ovaries in order to make informed decisions about their pet’s health.
