ARG!

I can't help but feel bad. My dog has mostly had people food, but he's 5 now and I want him to be with me a long time. So, I started feeding him really healthy dog food with lots of vitamins and stuff. Just a bowl a day with his usual food too. But he developed this rash and started getting these allergy symptoms. His groomer said she sees it all the time, and to put medicine on it and get him some benadryl and he will be fine. But a couple monthes goes by hand he keeps getting sick.
When I was low on money I had to stop giving him his dog food and he started getting better. When I finally took him to the vet she said he has a wheat allergy that no one caught before because he has always just eaten what everyone else eats.
I feel so bad. When I just treated him like a person, he was so much healthier! But I had to grow up and realize he needed dog food, and made him sick. Its really hard to make since of for me. But the vet gave him RX dog food that has all these healthy things in it and she said he could still eat people food, but he needs a cup of this every day to stay healthy and never ever give him wheat or gluten.
I can't believe he will never be able to lick my pancake plate again, poor thing! So sad...
