Petaluma vs. Natural Balance LID Vegetarian: Plant-Based Dog Food Compared
Natural Balance has been around since 1989 and its Limited Ingredient Vegetarian formula is one of the most widely available plant-based dog foods on the market — which is exactly why dogs end up on it. It's accessible, affordable, and it works as a starting point. But if you're wondering whether there's a more nutritionally robust option in the same category, this post walks through the two products side by side so you can make an informed call for your dog.
Quick Answer
Both Petaluma and Natural Balance Limited Ingredient Vegetarian are 100% plant-based and AAFCO-complete for adult dogs. The key differences: Petaluma is oven-baked (not extruded), has 50% organic ingredients, delivers significantly more protein (27% vs. 18%), and carries B Corp, Climate Neutral, and 1% for the Planet certifications. Natural Balance has wider retail availability and a lower price per bag.

Ingredient Breakdown
Ingredient lists are ordered by weight before cooking, so what comes first matters most. Here's how the two formulas stack up.
Interactive Ingredient Comparison
One difference worth noting: the first three ingredients in Natural Balance LID Vegetarian are brown rice, oat groats, and barley — all grains — before reaching peas and potato protein. In Petaluma, organic chickpeas lead the list, followed immediately by potato protein and pea protein, meaning protein sources appear higher in the ingredient order. Petaluma also includes marine microalgae as a direct source of omega-3 DHA, while Natural Balance relies primarily on flaxseed for omega-3s (ALA, which dogs convert less efficiently to DHA).
Guaranteed Analysis & Nutrition
| Nutrient | Petaluma | Natural Balance LID Vegetarian |
|---|---|---|
| Crude Protein (min) | 27% | 18% |
| Crude Fat (min) | 13% | 8% |
| Crude Fiber (max) | 6% | 5% |
| Moisture (max) | 10% | 10% |
| Calories | 3,650 kcal/kg (~395 kcal/cup) | ~3,330 kcal/kg (~374 kcal/cup) |
| Omega-3 (min) | Includes preformed DHA (marine microalgae) | 0.30% (ALA from flaxseed) |
| Taurine | ✓ Added | ✓ Added (0.1% min) |
The 9-point protein difference is meaningful, particularly for active dogs or seniors who benefit from higher protein to maintain lean muscle mass. Both foods are AAFCO-complete for adult maintenance and both add taurine — an important amino acid for cardiac health that plant-based diets must supplement.
How Each Food Is Made
Natural Balance LID Vegetarian is produced using extrusion — the same manufacturing process used by the vast majority of conventional dog food brands. Ingredients are ground, mixed with water, and forced through a die under high heat and pressure, forming the familiar uniform kibble shape. Extrusion is efficient and shelf-stable, but the temperatures involved (often above 150°C / 300°F) can degrade heat-sensitive omega-3 fatty acids and some vitamins, which typically need to be added back in synthetic form afterward.
Petaluma is baked in conventional ovens at lower temperatures — more like how you'd cook at home. This gentler process preserves more of the natural fats from whole ingredients like organic flaxseeds and peanut butter, and results in a softer, toasted texture rather than hard uniform pellets. It also means the food contains recognizable whole-food pieces rather than a uniform ground mixture.
Petaluma is manufactured in a solar-powered facility in the U.S.
Certifications & Brand Values
Natural Balance has been in the market for over 35 years and is now owned by Nexus Capital Management. The brand does have a "Feed with Confidence" batch-testing program and a customer care team of Registered Veterinary Technicians, which is a genuine differentiator for pet owners with questions. It has wide retail distribution — Chewy, Petco, Walmart, Amazon — making it easy to reorder.
Petaluma is an independent, bootstrapped company with a different credential profile. For pet owners who care about brand accountability and environmental impact, Petaluma holds B Corp Certification, Climate Neutral Certification, and 1% for the Planet membership — third-party verified commitments to social and environmental standards that Natural Balance does not carry.
Neither brand is wrong for being what it is. But if certifications and sourcing transparency matter to you alongside nutrition, that's a material difference between the two.
Cost Comparison
Natural Balance LID Vegetarian is one of the more affordable plant-based options on the market — one reason it's so widely used. Petaluma's cost reflects its organic ingredients and smaller-batch baked production. Cost per 100 kcal is a useful apples-to-apples comparison since caloric density differs between the two foods (Petaluma at 3,650 kcal/kg vs. Natural Balance at ~3,330 kcal/kg).

Switching from Natural Balance to Petaluma
Because both foods are plant-based, dogs already accustomed to plant protein typically transition with less digestive disruption than dogs switching from a meat-based diet. That said, it's still good practice to do a gradual transition over 7–10 days — start by mixing a small amount of Petaluma in with Natural Balance, then increase the ratio daily until you've fully switched over.
One practical note: because Petaluma has a higher caloric density and higher protein, you may feed a slightly smaller volume than you were feeding with Natural Balance. Check the feeding guide on Petaluma's bag for your dog's weight.

Is Natural Balance Vegetarian a complete and balanced dog food?
Yes. Natural Balance Limited Ingredient Vegetarian is AAFCO-compliant for adult dog maintenance. It is not formulated for all life stages and is not suitable for puppies or pregnant/lactating dogs.
How does Petaluma's protein compare to Natural Balance Vegetarian?
Petaluma provides a minimum of 27% crude protein versus Natural Balance Vegetarian's 18% minimum. Petaluma's primary proteins are organic chickpeas, potato protein, and pea protein, all appearing in the top ingredients.

No. Natural Balance LID Vegetarian contains no certified organic ingredients. Petaluma uses over 50% certified organic ingredients, including chickpeas, oats, sweet potato, flaxseeds, barley, and peanut butter.
What is the difference between baked and extruded dog food?
Extruded food (like Natural Balance) is produced under high heat and pressure, which shapes the familiar kibble and creates a shelf-stable product, but can degrade some heat-sensitive nutrients and omega fatty acids. Baked food (like Petaluma) uses oven baking at lower temperatures, preserving more of the natural fats and flavors in whole food ingredients, and results in a softer texture.
Can I switch my dog from Natural Balance Vegetarian to Petaluma?
Yes. A gradual 7–10 day transition is recommended for any new food. Because both are plant-based, the adjustment is typically smoother than switching from a meat-based diet. Petaluma's higher protein and caloric density means you may feed a slightly smaller serving by volume — check the feeding guide for your dog's weight.
