My senior dog develops allergies to any meat protein she eats for too long (chicken, beef, pork, venison, boar, fish, squid) and she's allergic to most grains (soy, wheat, corn, alfalfa). She's always done well on kangaroo but it as hard to find in a diet she could eat since alfalfa or chicken or some other added ingredient would set off itching, hair loss, and upset stomach. When she could no longer eat the last food she wad on I was so happy when I found this food. And so was she!! She's a13 year old lab mix and she's dancing with excitement again at meal time. She loves this food and has no allergic reactions to anything in it over the past couple months she been eating it. I stupid giving her joint medicine because the glucosamine in this food seems to be enough. I also stopped her krill supplements since the probiotics and lack of allergens in this diet have her regrowing a healthy, beautiful coat again. She's happy and healthy so I'm happy too!
