I have Cavaliers, who by nature of the breed, can have heart problems. One of mine has a murmur, last time assessed at a grade 2. As far as I know, atm, the other one is currently fine. My oldest was heart clear until about 10 years old and then I was told she had a grade 5 murmur and probably heart disease. She actually never really had any problems of note, though, with her heart. She just recently passed to the bridge at 12 years old, but it wasn’t her heart….she had a neurological disease (SM) that Cavs also are prone to and that caused her death. Actually, having a Cavalier reach double digits in age is great! Anyway, on to your question……while I don’t feed a “heart diet” I do try to feed as top of the line food as I can (which my holistic vet is fine with). I know that prey raw or homemade is probably the best, but either is not my choice. I have fed a variety of different kinds of food over the years. I’ve fed premade raw, freeze dried raw, dehydrated raw, canned and kibble. I’m currently feeding Acana Singles (Duck & Pear or Lamb & Apple) topped with either Primal or Stella & Chewy’s freeze dried raw or The Honest Kitchen Embark. Sometimes I top with canned foods like Instinct, Wellness Stews, Weruva, etc. I was using Merrick grain free kibble until I had an issue with a bag of the Pork grain free (strange looking and colored kibble pieces caused diarrhea). I’ve also used Merrick canned but have decided to go away from them, too, as they contain carageenan, and ingredient I’m not too comfortable with. I do know about BPA in cans, as well, and that’s why I like the freeze dried or THK. With each kind of food I have often supplemented with a heart targeted supplement (again at the advice of my holistic vet, who btw carries Nature’s Variety in his clinic). Some of my favorites are: Bio Cardio, Cardio Strength, Nature’s Farmacy heartwise and Standard Process Cardio Support. I’ve also given pre/probiotics and enzymes which I think can’t hurt. The heart supplements often contain things like COQ10, hawthorn, taurine, L-Carnitine and omega 3’s. You could also supplement these things individually. Please note that I’m not a vet, but a furmom with babies that more often than not have heart issues. I hope this helps some and gives you something to think about. 🙂
