Hello! I’m not sure how helpful this still is – I was reading through this thread before even noticing you posted more than 10 years ago haha I honestly could recommend either valu pak dog food from Jeffers. Its good for 200 cups. This usually lasts me about 3 months and sometimes longer cause I like to mix homemade food with it but if you need 10 cups a day that span will be shorter. It’s $41 for 50 lbs. I’m not sure if it’s a budget option for you now though.
Another good option could be Pet Supplies Plus that have 5lb bag for $19 or the Purina dog food from Target. I sometimes buy the 8lb one priced at about $16.
Best of luck with your food adventures for your dog 🙂
