Karen, I seem to have offended you in my comments and 100% did not intend to. I read the article posted - I agree with it. I, too, fed grain free with my doxies for years (Merrick GF Buffalo) and went through a stressful food search both before and after I got Brodie because Shelties require a lower protein diet and GF is def not low protein. I am no longer feeding grain free, I do not support it any longer not so much as it wasn't a GREAT food for my doxies, but because it will not be a great food for my sheltie. However I am not feeding the Purina or RC that my vet recommends. Every vet I've known in my 50+ years has always suggested Purina, Hills and in the recent 20 years RC has been added to the list. I love my vet, she is awesome in every way, but most folks trained with animal care are simply NOT trained in animal nutrition.
I don't know which BB kibble you are feeding, nor do I know which RC kibble was suggested and I don't need to know either. I only say to educate yourself. Your cardiologist most likely isn't a trained animal nutritionist even if she is an absolutely wonderful cardiologist. So educate, read labels, compare what you have and what is being suggested, look at the problem products with heart issues, look for beneficial supplements for heart issues. Why did she recommend RC? Is there any rhyme or reason behind her thinking or was it the rote recommendation that you often find with folks in the animal care as noted in that article. If it is a matter of supplements missing in BB, are there those you can add in without changing a food he that is working well for him?
In the end - pay attention to Sandstorm and do what you feel is best. He is your dog, and those here, vet, cardiologist, no one knows him better than you.
