"One of my Great Danes (I had a brother and sister) developed multiple allergies--food, environmental, seasonal--at about one year old. His skin would break out in horrid, red splotches and his hair would fall out. My vet diagnosed him with allergies, and since we weren't sure at that point WHAT he was allergic to, she thought we should start with the most common/obvious cause, food. So for a whole year I fed him nothing but prescription dry food, which consisted of nothing but fish and potatoes. He did great on that!
However, his sister refused to eat her normal food--she figured, hey, if my brother gets that special food, that's what I want, too! And feeding TWO Great Danes prescription food that cost $50 for 30 pounds--which they went through in less than a week--was just a tad bit expensive. After a year I asked my vet if I could try a non-prescription allergy formula, and she agreed with the caveat that if my [male] dog had a return of his symptoms we'd go back on prescription food.
I looked around, read a lot of labels, and finally decided to give Nature's Recipe Vegetarian Allergy Formula (as it was then called) a try. That was 7 years ago and I've never looked back. He--and his now deceased sister--loved it, whether fed dry or with the addition of canned food. (Although I'm vegetarian, and was thrilled to find a veggie food for my dogs, I did gradually add meat back into their diet because they are, after all, dogs.) He eats one dry meal in the morning and one with a can added at night, and he's doing great.
My 'baby' is now elderly by Great Dane standards--he just turned 9 earlier this month--but thorough exams (including lab work, x-rays, ultrasounds, and more) have caused my vet to proclaim him to be "in excellent health, not just for a SENIOR dog, but for ANY dog." :)
I highly recommend this product. I really can't say enough about how good it is."
