Puppy Mathematics

How Many Is Too Many?

This assumes the male dogs are not responsible for any unwanted litters. One male dog can sire 750 offspring in his lifetime. Add that to the numbers below (which are VERY conservative) and the problem is unbelievable.

This is why spaying/neutering your pets (dogs AND cats) is so very important.
