I had to convince my husband to feed our dogs raw food back in 2010. I wanted to start our dogs on raw. Finally he agreed to trying it. Now he and I would never feed any other way.
Our typical week consisted of chicken in the morning alternating with heart or beef or lamb or salmon for dinner. For organ meat we tried kidney but neither dog liked it. So it was liver all the way. They got occasional eggs and preferred hard boiled, especially one of dogs. He loved to suck the yolk out through a small hole he placed in the side of the egg. For bone we fed chicken breast, however we found with a rescue that this was too much bone for her. So we cut back to bone once a week in the form of turkey necks.
Sometimes we'd add yogurt or cottage cheese or scrambled eggs. Sometimes they had fruit usually blueberries which were a favorite. Although Barnum loved any kind of fruit including oranges and grapefruit and strawberries. Unusual for a dog to like such tangy fruits. And we also fed them vegetables as well, cooked and mashed if needed. Bailey had his favorites: peas, lima beans, French-style green beans, and carrots and peas. His all time favorite was brussel sprouts.
I do know a Leonberger owner who only feed chicken breasts to her dog. No organ meat. Her dog lived to 12 years of age. Rare for a Leonberger who usual life expectancy is between 6 and 10 years, usually more like an average of 8.
I do believe that is why Bailey lived as long as he did with bone cancer. He had been on the raw diet since he was 2 years old. That's one of the recommendations for dogs with cancer is to switch to a raw diet.
Our next Leonberger will get fed raw from day one.
Our dogs' teeth remained sparkling white after the third week into the raw diet. The rescue Leonberger we got had the most terrible teeth. After three weeks on the raw diet her teeth were white as can be. She was eight years old.
