The treat aisle at a pet supply store is genuinely overwhelming. The packaging is designed to communicate health, happiness, and your dog's unbridled enthusiasm — not to give you useful information about what's actually inside.
I've started asking clients to bring in the treat packaging from things they're currently giving their dog. It's usually illuminating. The front of the bag often says something like "natural," "wholesome," or "real chicken" — and the back lists 23 ingredients including three forms of corn, two artificial preservatives, and a calorie count that doesn't appear anywhere obvious.
Here's how to actually evaluate what you're giving.
Start with the Ingredient List
Ingredients are listed in descending order by weight before processing. The first ingredient has the most weight; subsequent items have less.
What you want to see first: A named protein source. "Chicken," "beef," "turkey," "salmon," "duck," "rabbit." Not "chicken flavor." Not "poultry." The specific animal, named.
Chicken flavor as the primary claim on the front of the bag, with "chicken" appearing fifth on the ingredient list behind several starches and fillers — that's a marketing choice, not a nutritional one. I see this often.
What a short ingredient list usually means: Simpler formulas have fewer places to hide things. That said, ingredient count isn't a quality metric in itself — some longer formulas are well-constructed and perfectly fine. But if you can't identify most of what you're reading on an ingredient list, it's worth pausing.
Ingredients Worth Flagging
Propylene glycol. A humectant used to keep semi-moist treats soft and chewy. It's generally considered safe at typical treat levels, but it's not necessary, and I'd rather see other moisture-retaining approaches.
Artificial colors (dyes). Serve no nutritional purpose in dog treats — dogs don't see the same color range we do and aren't choosing treats based on appearance. Red 40, Blue 2, and similar dyes appear in some treats. They're not proven harmful in dogs at typical exposure levels, but adding them is a pure marketing choice, and I'd rather they weren't there.
Added sugar. More common in commercial treats than people realize, usually listed as molasses, corn syrup, or cane sugar. Dogs don't need added sugar. It's there because it makes food taste good to dogs (yes, dogs do have some sweet receptors, unlike cats). It also promotes dental issues and contributes empty calories.
High sodium. Treats marketed for training are sometimes high in sodium to enhance palatability and shelf life. This matters more for dogs with cardiac or kidney conditions, but I'd avoid high-sodium treats even in healthy dogs as a precautionary habit. The National Research Council puts the safe upper limit for dietary sodium at around 15 grams per kilogram of dry matter, with adverse effects — vomiting, fluid and electrolyte shifts — showing up above roughly 20 grams per kilogram. No single treat gets a healthy dog anywhere near that on its own, but treats stack on top of a commercial diet that's often already formulated close to the daily target, which is the actual reason I care.
BHA, BHT, ethoxyquin. These are artificial preservatives used in some pet foods and treats. The evidence on their safety at typical pet food exposure levels isn't definitive, but given the availability of alternatives (mixed tocopherols — vitamin E — as a natural preservative), I'd choose treats that don't contain them when possible.
Undisclosed "natural flavors." Can include almost anything — meat derivatives, plant extracts, animal digest. It's not inherently problematic, but it's opaque. For a dog with known food allergies or sensitivities, an undisclosed "natural flavor" is worth asking the manufacturer about.
Treat Types That I Actually Like
Single-ingredient dried or freeze-dried meat treats. Just chicken breast, just beef liver, just salmon — freeze-dried or dehydrated, no additives. These are about as transparent as treats get. The calorie density is generally manageable per piece. Palatability for most dogs is high. If you want to know exactly what your dog is eating, this category answers that question completely.
Plain vegetable pieces. Not as glamorous. But small pieces of carrot, cucumber, cooked sweet potato, or plain pumpkin can serve as low-calorie training rewards for dogs who find them motivating. Some do, some don't — Beagles, in my experience, will accept basically any food enthusiastically, while some terriers look at a piece of carrot with the expression of someone who was expecting filet mignon.
Dental chews with verified efficacy. I distinguish these from general "dental treats" because only some have evidence behind the dental health claim. Look for products that have been evaluated and accepted by recognized veterinary dental organizations. The treats in this category actually reduce plaque and tartar through mechanical action combined with specific ingredients — they're not just flavored chewing objects.
Functional treats with real evidence. Probiotic-containing treats from reputable manufacturers who specify the bacterial strains and CFU counts per treat can genuinely support gut health. Omega-3 enriched treats from sources with good manufacturing standards can help. The bar for "functional" should be: is there a published trial in dogs showing a measured effect, or at minimum a biologically plausible mechanism with good analogous evidence? Marketing claims don't meet that bar.
Treats I'm Cautious About
Jerky treats, especially imported ones. There were significant safety concerns raised about imported jerky treats and illness in dogs, investigated over multiple years by regulatory agencies in several countries. The investigation produced no definitive single explanation, and some products were removed from market while others continued. I'm cautious about jerky treats that don't clearly specify their origin and manufacturing location, and I'm most comfortable with products manufactured domestically in regulated facilities.
Very hard chews. Certain chews marketed as long-lasting dental aids are hard enough to fracture teeth. I've extracted fractured teeth caused by hard chews — it's an entirely preventable injury. The guideline I use: if you press the item against your thumbnail and can't make a dent, it may be too hard for safe chewing. Antlers, certain thick bones, and some very dense synthetic chews fall in this category for many dogs.
Treats sized for large dogs given to small dogs. Partially a safety issue (choking), partially a calorie issue. A treat portion appropriate for a 70-pound Labrador is proportionally enormous for a 10-pound Chihuahua. Some owners don't think about size-appropriate portioning for treats the way they do for kibble.
The "Natural" Label Question
"Natural" on a pet treat has a loose regulatory definition — essentially meaning that ingredients were derived from natural sources rather than being entirely synthetic, but it doesn't mean organic, unprocessed, or free of preservatives. "Natural flavor" and "natural preservatives" are common on products with complex additive lists.
I don't trust "natural" as a quality signal. I look at the ingredient list. The word on the front of the bag is marketing; the list on the back is information.
For Dogs with Special Needs
If your dog has confirmed food allergies, the allergy considerations override everything else — you're specifically choosing treats that exclude the allergen and come from trusted manufacturing sources. The criteria I described earlier all still apply, just after the allergen screening.
For dogs with cardiac or kidney disease: low sodium is especially important, and phosphorus control may matter for kidney patients. For overweight dogs: calorie density and portion size matter more than almost anything else. For senior dogs: dental treats become more important as dental disease risk increases with age, but treat calorie budgets may need to shrink alongside reduced daily calorie needs.
Not every dog needs the same treat strategy. The criteria above apply broadly; the specifics need to match the individual dog.
