Most dogs with either allergy or skin problems will benefit from a fish-based diet. Fish-based diets contain omega 3,6 fatty acids which act as natural “anti itch” fighters no matter what the origin of the itch. A diet change will take several months to elicit an effect but overall isn’t it much better to control an itching problem with diet and not medications?! When choosing a diet, please consult us or your veterinarian. ALL pet food manufacturers will tell you their food is the best, but do you know some pet food companies do not even test feed their food to dogs? Be sure to ask the pet food company that question if you’re considering feeding their food. Also ask to read any scientific studies they may have done—you will be surprised at how many do not actually feed their food to dogs AND have no research to backup the claims with their food they are manufacturing!
