I have two Chihuahuas; one that's very light in color. He has had tear stains under his eyes ever since I got him. Two weeks after starting Freshpet, the stains are totally gone. I know that they're caused by a bacteria that reacts with the tears and causes the stains. Now there's not even a trace of a stain. Needless to say, they love Freshpet food. I just wish that you made it in bigger bags for those who own large or multiple dogs. I've fed Royal Canin, Blueu03beBuffalo, Taste of the Wild, and even 4Health brand cat food in the past but they definitely love Freshpet the best. Feeding your food is also a lot less labor intensive than trying to feed a truly balanced food that I would make myself. Definitely a 5 star food!
