I hope this helps, PuppyPalace...
Our dog, Buddy, was on Costco's Kirkland Lamb and Rice. It's super easy on the wallet and it was an okay food. He was going through it like there was no tomorrow though and we were buying a lot of it.
So, under the advice of Mordy (who we consulted after Buddy became ill) we changed him to California Natural and he is absolutely stunning. He has filled out nicely, he is lean and is in the best shape he's been in, ever. He's also healthy (knock on wood).
Now, California Natural is much more expensive than Costco. We pay about $30 for a 36# bag (whereas Costco was $15 for a 40# bag). However, we feed
much less of the California Natural. We started a new bag of CN for him a month ago and he still has another 3 weeks (possibly another month) left of that ONE bag (and this is an 85# dog we're talking about here!).
$30 bucks for two months (and 1 bag of food) or $45 for two months (and three bags of food)?
I really hope that you can get samples or at least check out some of the better quality foods out there. Eagle Pack and products by Natura (Innova, California Natural) are pretty good.
Good luck and I hope you find a suitable food for your pup.
Also wanted to mention that our new addition, Banzai is on Innova and he is doing very well on it. Buddy needs to have a simpler formula that is easy on his tummy, which is why we have him on CN.
