In addition, I add a large can of pumpkin for my boxer's sensitive tummy...helps with the boxer gas. I will also cut up sweet potatoes as well.
I don't do as much meat - too much protein for the boxer causes some weird aggression - aggression showed up out of the blue (I thought) and I took her to the vet...we talked about diet, I let her know that I had increased the protein. She recommended cutting back on the protein, so I did and the aggression is almost. I do about 30% protein, 50% veggies, 20% brown rice or whole wheat pasta. My pups also like oatmeal with apples (no seeds), plain yogurt with pineapple, eggs (scrambled, boiled, etc). I use any kind of greens from the farmer's market - kale, turnip greens, spinach, etc. Brussel sprouts on occasion. The don't get the oatmeal often - really only if I make it for myself on the weekends, I will make extra and add apples to their's for breakfast.
In the summer I give them watermelon (not large quantities, but a few chunks). I always share bananas with them, too.
I have a cookbook I found online a few years ago. I'll try to dig it up and get you the name. Had tons of recipes if you ever wanted to switch it up a bit.
I've been cooking for my dogs for about 5 years. Perfect blood work, healthy coats, clear eyes, no stinky dog smell. My vet is always super impressed by their health. My rainbow bridge pup lived to 16 after being diagnosed with cancer at around 10. Vet recommended getting rid of kibble and start cooking and that's what I've done ever since for all of them.
