What dog food?

[jl1966]

I recently was fortunate enough to have a golden retriever come into my life, she is 4 years old and her name is Betty. I got her from a guy who kept her in a kennel constantly. He got her for his little girl, and once the girl lost interest the dog stayed in the kennel. Anyway, she now has a 3 acre fenced yard to run, roll, and do all the stuff dogs do. When we first got her the wife was not sure about her, and I was afraid either the dog, me, or my wife was gonna have to go. we have all that ironed out now and I am still married, and the pooch is part of the family now. The question is what is a good all around food for her. We started out with a big bag of Wal-Mart Ol Roy food. The vet said that was maybe not the best stuff, not nutritionally dense enough. She suggested something by Purina, like ONE, or pro plan, or something by Iams. She is not really going to be a hunting dog, just a pet, intruder alerter dog. This is the first dog I have had in awhile, we moved to a bigger place about a year ago, and I have been looking for the right dog for awhile. When I was a kid we fed all the dogs Purina dog chow, coon dogs, rabbit dogs, bird dogs, and pets, all got the dog chow. Of course we also used to carry whichever dog was in service that day in the trunk of the car, dad didn't have a truck, and did not believe in coddling a dog. Anyway what do you all feed your dogs. The requirement is that it has to be easily available and not outrageously expensive, no vet only food, or doggy gourmet stuff please.
Thanks.
