Walk down the dog food aisle and youβll see βgrain-free,β βholistic,β βhuman-grade,β and a dozen other labels competing for attention. Some of it matters. A lot of it is marketing. We sat down with Dr. Rollins, a veterinary nutritionist, on the We Are The Cure Podcast to separate the two.
What actually matters on the label
Look for a named protein source (chicken, beef, salmon) as the first ingredient, not a vague βmeat by-product.β Check for a statement that the food is formulated to meet AAFCO nutrient profiles for your dogβs life stage, the baseline guarantee that a food is nutritionally complete. And match the food to life stage: puppies, adults, and seniors have meaningfully different needs, particularly around protein and calorie density.
The grain-free lesson: a cautionary tale worth knowing
A few years ago, grain-free diets dominated the market, often marketed as healthier or even cancer-protective. According to Dr. Rollins, that push was driven almost entirely by marketing, not medical evidence. The unintended consequence: many manufacturers simply swapped grains for high levels of legumes like peas and lentils. In dogs eating diets marginal in protein and taurine, with a lot of that protein coming from legumes, researchers began noticing a possible association with dilated cardiomyopathy, a serious heart condition. As Dr. Rollins put it, the relationship is βmultifactorialβ and βvery complicated,β likely involving both genetics and diet, and still not fully understood. The bigger lesson: when a pet food company markets what a food doesnβt contain, itβs worth asking whether there was ever a real reason to avoid it in the first place.
If you want to cook at home, do it the safe way
Homemade diets can absolutely work, and veterinary nutritionists build them for clients regularly, often to manage specific medical conditions. But thereβs an important distinction: a professionally formulated homemade diet is complete and balanced, with the right vitamins and minerals added in. An ad hoc homemade diet (say, sweet potatoes and lamb) usually isnβt, and can quietly cause nutrient deficiencies over time.
If you want to explore home cooking, Dr. Rollins recommends starting at balanceit.com, a resource built by a board-certified veterinary nutritionist that provides complete, balanced recipes along with the supplements needed to round them out. For anything more customized, especially for a dog managing a medical condition, a consultation with a veterinary nutritionist (often available via telemedicine nationwide, with a referral from your regular vet) is the more reliable path.
A few other things worth knowing
Exotic proteins arenβt automatically the answer to allergies. Duck, venison, and elk diets have become popular for dogs with suspected food allergies, but Dr. Rollins flags a real issue: unless a manufacturer thoroughly cleans equipment between production runs, an βelkβ diet may still carry trace contamination from a chicken diet made on the same line, similar to how peanut cross-contamination works in human food facilities. True food allergy diagnosis typically requires an elimination diet or a hydrolyzed protein diet under veterinary guidance, not just switching to a novel protein off the shelf.
Salmon is great, but not as a sole protein source. Itβs an excellent source of omega-3 fatty acids, but a diet built entirely around salmon can push vitamin D too high, since dogs are more sensitive to excess vitamin D than humans. Itβs usually paired with a second protein source for balance.
The 10% rule for treats and table food. If you want to share human food or treats, keep it under 10% of your dogβs total daily calories. Go beyond that regularly, and you risk throwing off their calcium and vitamin balance, even if the extra food seems harmless.
The bottom line
Good nutrition doesnβt have to mean chasing the latest trend. A named protein source, AAFCO life-stage certification, and a healthy weight and coat are strong everyday signals youβre on the right track. For anything more specific, whether thatβs a medical condition, a suspected allergy, or questions about your dogβs diet during cancer treatment, a conversation with your vet or a veterinary nutritionist is worth far more than another label claim.
