Kinetic Performance Mass 34K Dog Supplement, 4-lb tub
Had to start with lighter mix to get the dogs started on it (it's very fishy) but once they did they absolutely love it. It really glosses up their coats and cuts down on shedding. That's a big deal with three Labs in the house.
Skeptical at first but works great. My Doberman went from 10-20lbs underweight to having muscle tone and ideal weight within 2 1/2 weeks. Great product. Would definitely recommend. Two thumbs up for me.
