The link between grain-free food and dog’s growing cases of DCM

Before we dive into what Science Diet Dog Food is all about, and why it is necessary for your dog’s health, let’s first know the reason why some pet owners are hesitant to try this stuff.

Dilated cardiomyopathy or DCM is a common canine heart disease that has been associated with grain-free foods, and according to a published article by the Journal of Animal Science, there is no truth behind this theory. After going through extensive studies, the link between DCM and grain-free foods has been debunked by the FDA. The Journal of Animal Science even stated, “While determining the cause of recently reported cases of cardiac disease is of the utmost importance, based on this review of the current literature, there is no definitive relationship (between) these implicated diet characteristics and DCM.”

Even though this alarming theory has been cleared up by experts, every pet owner needs to do their research first before believing things that they find on the internet. Remember, pets are living beings, and they deserve to be treated with the same care as a human does. Now, if you’re still hesitant to try Science Diet Dog Foods, then I suggest you keep reading.
