What diet and supplements are safe for my Cav's heart health?

Updated on September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Male | unneutered | 1 month and 23 days old | 9 lbs

Based on our research, we know that Cavs are particularly prone to heart disease. We are thinking of adding raw foods to supplement Niko's diet. We were thinking of rotating thru olive oil, fish oil, carrots, raw eggs and sweet potato– is this okay? Also, Is there anything else we can do or give Niko that would keep him heart healthy?

I would not recommend giving Niko raw eggs. Raw eggs are not safe to feed him, and there is the risk of poisoning from avidin, which is a protein in raw eggs whites. Excess avidin interferes with the functioning of biotin in the body, which in turn is essential for the growth of cells, metabolism of fat, and transference of carbon dioxide among other things. You can feed him hardboiled eggs with no shell instead.

I would also causing against using too much olive oil, as that will lead to pancreatitis. Too much fish oil interferes with wound healing. Use sparing amounts of olive oil, and you can give Niko 1,000 mg fish oil containing 300 mg of EPA/DHA combined for every 30 pounds of weight.

To keep him heart healthy, do not over feed him, make sure he is on a high quality puppy formulated food, and take him out for regular exercise.
