Food & NutritionDo heart and gut supplements benefit my Cavalier King Charles Spaniel?
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.
