Well some people would prefer to avoid chemicals and medications like Frontline for their dogs, that's why the look for alternative methods.
I myself have my dog on a raw diet. When we first bought him, he had relatively normal puppy energy but the shedding was UNBELIEVABLE! I am guessing it was the Aussie Shepard in him but I mean...piles and clumps and loads of hair dropping off this dog! Didn't help that I have a dog allergy to some types of hair, or just large amounts of any kind of hair so i was having troubles!
He gets chicken, beef and sometimes pork and fish. He also gets eggs, brewers yeast ( sprinkled on his food, he LOVES it) and either just raw garlic, or garlic powder. We have never had a problem with fleas so far, and he spends a good amount of time outdoors and with other pups around the neighborhood.
He also gets a dog multivitamin once a day. It helps ALOT and the shedding? Has almost completely stopped! Hallelujah!
