Omega 3 fatty acids for pets can help with heart health. Royal Canin makes a diet for dogs with heart disease. Lastly, it is not fully understood, but there appears to be a link between grain free dog food and heart enlargement. If you are feeding a grain free diet, you may talk with your veterinarian about a diet change. I hope this helps.

Hi there and thanks for posting. Although there isn't a food that is formulated for all three medical issues you listed, but there are separate foods for sensitive stomach/skin and cardiac disease. Prescription diets by Royal Canin or Hills such as Hill's Z/D Diet or D/D or Royal Canin's Ultamino Diet or their Cardiac Formula would be ones I would recommend. I hope this helps and thanks for using Petco Pet Education Center, formerly Petcoach!

I certainly understand your concern. I would use a skin sensitive food like Royal Canin Dog Sensitivity. Royal Canin is not a brand of food that the FDA has implicated in this rise of heart disease in dogs.

Royal Canin diets are all formulated with pre-biotics which help support a health gut bacteria. You could add in an additional probiotic but you may not see a huge amount of benefits BUT it will not hurt anything. Purina makes a very nice probiotic called FortiFlora and that would be the one I recommend. The Bio-Cardio may be beneficial but to the best of my knowledge, no testing has been done to know for sure if this is effective or not. Royal Canin does make a diet specific for Cavaliers that has additives for heart heath. They also make a diet for pets with heart disease or even just heart murmurs. They have done some studies indicating that these diets do impact heart health. Your fatty acid supplement does help to maintain heart health through its natural anti-inflammatory properties. I would recommend to look into the other diets and discuss with your vet if these may be good option for Chloe. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.

I'm so glad to help you and that you like my answers! Royal Canin is an excellent food, and the 25% is fine for Chloe. Yes, you are right Cavaliers can be prone to heart disease, so the extra amino acids are good for them. Chloe is lucky to have you!
