Find him something with a bunch of peas and/or other legumes. Grain free is thought to be less of an issue that “pulse ingredients”.

Welcome to the forum! I think Tagrenine meant find him a food WITHOUT peas and legumes.

The concern is that there was a recent rise in reports of food-related dilated cardiomyopathy (DCM), a serious heart problem. The cause is not yet known, but there seems to be some sort of correlation with dogs being fed grain-free foods (primarily kibble) long-term. The current thinking is that the problem isn't so much the lack of grain but the presence of a large quantity of peas and other legumes (which are added to the food instead of grains in order to prevent the kibble "batter" from gumming up the extruders, as well as to boost the protein content and reduce the chance of mycotoxins).

I took a very quick look at the Open Farm website and didn't see anything alarming there, but you may want to tell us what variety you are feeding him. One of the most important things you need to check is the "AAFCO" statement, which should say something like: [Pet Food Name] is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for growth/all life stages including growth of large-size dogs (70 lbs or more as an adult).

I've raised my last three dogs on raw and personally believe it's best for them, as long as it is nutritionally balanced. However, this is a controversial topic so you will hear many different opinions on the topic and will need to do a lot more independent research to do it well.
