Dogs also have food allergies similar to humans, and 67.5% of dog owners know that they have food allergies (Aisia survey). Food allergy in dogs is said to be caused mainly by proteins contained in food, but which protein is different depending on the dog. As food care for dogs with food allergies, it is important not to give the food that is causing them. It is considered effective to provide only one type of protein source suitable for each dog, and to give proteins that have been degraded to peptides and amino acids by enzymes etc. so that they are not easily allergenic. The newly released "KEN KEN PURO" is food-friendly dogs, and the raw materials are made only with "Tuna", "Skipjack". In addition, coloring and coloring agents are designed without additives for safety and security, and are carefully manufactured in JAPAN.
