There are thousands of dogs being euthanized each and every day. Most ads that appear are backyard breeders and the world does not need dogs being offered to stud - for the owners to make money - to create more puppies that will most likely end up in kill shelters. The shelters do not receive enough funding and are overflowing with unwanted dogs. Many of the buyers do not spay their animals, which only adds to the increased overpopulation. Ads to sell dogs are prohibited, but are appearing across the country each and every day. Craigslist must take responsibility to see that these ads, which they prohibit, do not get posted!
