Ok, this is what I was told and I'm not saying it to upset anyone. I was told that if you can buy it at a supermarket, it's PROBABLY not the best food. If your dog is doing well then you might not want to switch, read the ingredients. Look for things like corn (a filler) or anything that says byproduct. If corn is in the first few ingredients listed I would suggest changing the food.

Personally I like Chicken soup for the dog lover’s soul. The ingredients are wonderful, but I know some dogs do better on it than others. Three of my four eat it and do wonderful on it (the fourth is a vegetarian on prescription food with a meat protein allergy) Their coats, which from the shelter and foster care, were dry and dull are now shiny and healthy. It's priced like Eukanuba, but has better ingredients.

Some dogs do well on food that I would consider bad. My childhood dog, Barney, lived to be 18 years old and when he was older he ate cycle 4 senior food (not even sure if it’s still made) that we bought at the grocery store. He was diabetic, which I suspect was from the poor (we didn’t know any better) food he ate when he was younger, still, he lives to a ripe old age.

Food for thought, no pun intended!
