Raising dogs, in particular providing care for the molossus, is old hat for humans. Historians theorize dogs were first domesticated sometime between 12,000 and twenty five thousand years ago—and that canines evolved from wolves. Since then, human beings have selectively bred more than 400 different breeds, which range in size from four-pound teacup poodles to Irish wolfhounds, who have earned the title of tallest dog. However, the most widespread dogs are non-pedigree dogs—the one-of-a-kind dogs known as mixed-breeds. The molossus is another favorite choice among canine owners. Many owners are unaware, however, of many critical molossus care tips.
