A wrong notion on dog waste:
While most people believe that dog waste can make a good lawn fertilizer, facts simply don’t support it. The accumulation of dog waste represents a health risk to both a dog and its owners. Dog waste contains bacteria from your dog’s digestive system that can be passed along to plants and humans can become very ill by eating fruits or vegetables “fertilized” with dog waste.

During a rainstorm, dog waste can easily get washed out of your yard, into sewers and streams. With contaminated water the bacteria in dog waste can cause cholera & dysentery if ingested. Dog waste in large enough quantities can even attract rats. Depending on what the dog has been eating his feces can also cause discoloration or burns in lawns.

A Brief History of the Dog:
While the details surrounding when the partnership between dogs and humans happened is still a controversial issue, it most likely happened somewhere between 10,000 and 15,000 years ago. Though it is still believed, and can be stated with some degree of certainty, that our relationship was one born out of necessity, no one really knows for sure why it happened. So it has become widely accepted that the dogs wanted shelter and a solid food source, and humans wanted companionship and protection.

Recognized dog breeds are a result of human selection, in that dogs were traditionally bred for specific functions. Most existing dog breeds began as mixed breeds, either by random occurrence or by deliberate crosses of existing breeds. While encouraging desirable traits and discouraging others, breeders sought to create the ideal appearance or behavior, or both for dogs. Additionally, this was done to ensure that the dogs could consistently produce offspring with the same appearance or behavior. Mixing breeds can lead to desirable results, especially in the hands of an expert breeder. On the other hand, inexperienced cross-breeders can produce disastrous results.
