Fresh meats, vegetables and fruits. Sometimes providing hot chicken soup. We also providing some tasty cookies to my dog.
We have 3. My girl cooks for them. Mostly chicken and turkey mixed with some quality dry food. They get chicken jerky for treats made in the oven. Last Border Collie was 16 and we had a Corgi that was 17 1/2.
I boil 10 pounds of leg quarters, 2 pounds of frozen mixed veggies, and a little salt. Each dog gets a splash of the broth and veggies, a leg quarter, and a boiled egg per day. We sprinkle a scoop of dog supplement for each daily. I am not sure what it is. The dogs fast on the last day of the month for health support. The last two dogs I lost were a 16 year old English mastiff and two 23 year old golden retriever/Anatolian crossbreeds.
