If your dog scratches and loses his hair and your vet throws up his hands and says allergic to fleas,don't believe him.your dog is allergic to thefood you are buying. And don't buy food at the vets,it is no better. Sure, some hardy souls can survive on it,but not the ones that scratch their hair off or have seizures or cancer or bowel problems or ahost of things that only god knows. Go to dogtorj.net read all.go to the health food store buy newman's own,petguard,myrick's or look at what they have w/ no wheat,corn,soy(people think its good,but its full of gluten and phytoestrogens and messes w/ your pancreas)or dairy products. THE major food all. ergen is wheat and dairy. That goes for people,too.My friends that sneeze to death in the spring, don't, after cutting back on the gluten. the pollen is just the thing that pushes them over the edge.
