Also poultry (chicken & turkey, especially) and lots of pork cuts are often enhanced with salt solutions... so check the sodium content. You want <100mg per 4oz serving. If you get the "enhanced, guaranteed juicy" varieties with lots of salt, you can cause digestive upset (i.e. runny poops).
My average is $2/lb... that's a mix of pork ($1.90) and beef ($3) along with whole sardines ($1.80) and mutton ($1.80). I joined a rawfeeding bulk buying group, which is AWESOME for finding great deals. You guys in Texas have much better deals at the store that I do.
And you do NEED organ meats for essential vitamins (but - eventually... wait a few weeks before introducing, to avoid runny poops)... in small quantities, to total ~10% of the overall diet over time.
I agree raw feeding is easy - once you have your system down. It took me a few months to get a system going... and also get Denna's system going. She now can eat pretty much anything I put in front of her (and will try anything... including citrus and hot peppers... dummy). My freezer is now stocked with mutton (bone-in), venison (boneless), beef ribs, bison kidney and lamb liver... and a few chickens and turkeys. I pull stuff out of the freezer weekly in a large 80/10/10 portion (~20lbs worth), then divvy up meals daily. ~1.5 lbs for breakfast (1lb boneless meat, 2oz liver, 2oz kidney, 2oz green tripe) and ~1.5lbs for dinner (1lb boneless meat, 0.5lb bone-in meat).
You probably want to stick with smaller more frequent meals with your puppy until he's ~1 year old.
Denna also loves all veggies, so in addition to a few eggs a week, she also occasionally gets sweet potatoes, broccoli stems, squash ends, carrots, etc... but absolutely NO onions (they're toxic).
Be sure to check out the "getting started" files... I know Deb and some others have posted some great links to complete "instructions" on how to get started with minimal excitement (i.e. runny poops and/or constipation issues).
