Although I am paying almost $70 a sack, $20 just for a 2.5 bag...
Wow , That is an expensive bag of dogfood. I think that would definitely be hard on my budget. As it is now we scrape to keep enough people groceries in the house

But I heartily agree with others, to feed what you feel most comfortable with and can afford. I feed Royal Canin Natural Blend, which has no corn but does have some rice. Still, overall I think it is a good food, the best I could really find in this area, and costs me about $30 for a 37.5 pound bag. The food review site rates the grade as human quality.

Most importantly though, the pups do well on it, look good, have energy, digest it well, etc., and I feel comfortable myself with it, so that is the way to go for me.

Pro-Plan actually is a better quality food than just about any grocery store brand dog food, I'd say better than Science Diet, Ol Roy, Pedigree and so on in my opinion. If that is affordable for you and you feel it would be good for Major, I would say go for it.
