Based on the quality of the PA rescue that was involved in the filming of Oprah's April 4th show, I would recommend you make an effort to watch or tape and watch later if:
You don't have a clue about puppy mills (and would like to have a clue).
You want a dog and are considering buying from a breeder or considering paying a price (other than adoption fee or donation) for any dog, any breed, any age, anywhere in the USA. (another option - research Petfinders who currently have 250,000 puppies and adult dogs profiled that are up for adoption).
I'm sure that there will be some "taming" of the film footage but I would advise caution if you are extremely sensitive to the plight of animals. I add this because after 20+ years of conditioning, I still become distressed to the point of being physically ill under certain circumstances, certain "triggers" that are my special torment. If you have a young child that is likewise very sensitive about animals, I'm not real sure I'd let them watch and certainly not alone. I have no way of knowing how far the filming about mills will go, but I wouldn't want to take that chance.
This is not about liking or disliking Oprah. She has a venue which reaches the people that need to get a clue about this and I applaud the effort. I am also not a fan of the State of PA lawmakers, politicians, etc., with regard to how they are dealing with animal problems in PA. However, as I've pointed out before, there are wonderful people in PA who are doing the right thing and many good rescues operating. I salute every rescue that is working toward stopping the insanity of abuse, neglect, and out of control breeding and population.
Yes, I know, there is a lot of insanity in the world every day. I also know that every day in this country, maybe in your neighborhood, a dog stops a burgler, a rapist, a murderer. Dogs are helping heal hearts and bodies, protecting our men and women in foreign countries and our police officers and civilians on our own dirt. They find heroin and coke and bombs. They search to find our lost loved ones. If you've ever owned a dog that you know would die for you if necessary, you know that there is no more unconditional loyalty to be found in this world.
I also know that every 9 seconds a dog dies in a shelter. These words don't make me sick. They break my heart. We can do better. Even if it's just 1 dog at a time.
