Did you know that Iowa ranks #2 nationally for having the most puppy mills? Its a sad true fact. What is a puppy mill you ask? Puppy mills are a facility that produces a mass amount of puppies. These dogs are housed in small cages, unsanitary living conditions and are usually very poorly vetted. Their goal is to produce mass puppies at little cost. Puppy mill dogs carry diseases and usually have many genetic defects. Do your research before you buy that puppy in a window of a pet store because chances are they are from a puppy mill. No reputable breeder would have a pet store sell their puppies because a reputable breeder will want to get to know the new owners.
