hello, I am new to the home cooked meals, My two have only been eating it for a week exactly tomorrow. This is what I have been them -
3 pound organic chicken (this batch added 1 pound hamburger also)
1 pound frozen organic green beans
about 6 organic fresh carrots (large sized)
5 organic white potatoes.
3 sweet potatoes
1 1/2 c lentils (for grain replace with rice,ect)
1/8 c olive oil
1 c cottage cheese
1 can PLAIN pumpkin
I add 1/2 tsp of ground flax seed along with other supplements to their bowls when serving.

I would like to mix it up a bit, is there any other grain free recipes out there?
They are 9 month old Dalmatian puppies so i am feeding them 3 cups each.
