Whoever started running Dr. Baker's account needs to stop. This is cringy and weird.
When scientists let dogs pick their own food, something surprising happened. The dogs did not reach for the starchy kibble most owners buy. Instead, they built their own meals that looked a lot more like what wolves eat in the wild.
In one careful study, dogs from different breeds were offered several foods at once. Some were high in protein, some high in fat, and some high in carbs. After the dogs had time to learn what each food did, they settled on a clear pattern. About 30 percent of their calories came from protein, 63 percent from fat, and only 7 percent from carbohydrate. The same balance showed up across breeds. They actively avoided the high-carb options and kept going back to the fatty ones. When food was unlimited, they also ate more total calories than their bodies strictly needed—an old “feast or famine” habit that helped wild dogs survive lean times.
A follow-up test that ran longer found the same idea. Dogs started by grabbing the fat-rich food first. Over the days they slowly added more protein, but carbohydrates stayed a tiny part of what they chose. Other work with free-ranging dogs shows they hunt for meat smells even when cheaper scraps are easier to reach.
These studies do not prove every dog should eat only raw meat. They do show that, given a real choice, most dogs still prefer a high-fat, moderate-protein, low-carb mix. That preference lines up with their ancestry far better than the carb-heavy bags sold at most pet stores.
