Forgive me if this has been shared already; but this is a favorite of mine to help educate folks about pet nutrition. It's an excellent expose on the pet food industry! The US actually pulled it from ever being aired here (it mentions many brands) but luckily this blogger bought a copy and is able to share it. If you have a spare 45 minutes to watch it you won't regret it! And please do share. Thanks!
