Unfortunately the internet is a pretty useless place to learn anything when you have people who google day and night. All theory with 80% actual BS,and invariably by those with vested interests.You can give 100 links for some view and I can tit for tat with 100 of mine.
I have always had to learn from actual science and use my brains,and practice it in the field BIGTIME.
What has starch or teeth cleaning got to do with CHD-and I’ve never had to get a dogs teeth cleaned.
Re causes of CHD-there are many points of circumstantial evidence pointing to nutrition as the main cause. Simply the CA/P ratio in a stricly balanced TOTAL dietary intake,with regard that CA is fully metabolised,and not lost due to VIT D deficiecy(sun exposure) and Vit C(dogs under strss do not produce enough), AND high protein acid leeching.
Nutrition is a very complex area and I don’t intend to attempt explaining it all,but the fundimentals are very simple as are most things.
I just comment here for the sake of over 2 million plus dogs who are diagnosed every year world wide(and their owners),with my 50 years of intimate experience.
You can take it or leave it,and carry on believing the scientific mumbo jumbo that has been peddled out for 80 plus years now.
‘Experts’ are people who know more and more about less and less.
