Dog Food 2025 Guide: Grain‑Free or Grain‑Inclusive?
The dog food landscape is entering 2025 amid sweeping changes in formulation and regulation. WSAVA’s updated nutritional guidelines, AAFCO’s new protein definitions and the macro‑nutrient revisions in Europe’s FEDIAF standards leave veterinarians and informed pet parents with one burning question: Grain‑free or grain‑inclusive? Drawing on peer‑reviewed literature and frontline clinical experience, this guide dissects every critical factor you should weigh when selecting dog food this year.
Snapshot of the 2025 Dog Food Market
1.1 Market Size & Trends
According to Euromonitor, Turkey’s dog food market reached ₺13.6 billion by the end of 2024. The projected compound annual growth rate (CAGR) for 2025 stands at 11 %. Grain‑free SKUs now account for 27 % of total revenue, while functional formulas (hypoallergenic, renal‑support, etc.) command 9 %.
1.2 Regulations & New Standards
- AAFCO 2023 Revision – Added the term monochrome protein; insect‑based proteins officially recognised.
- FEDIAF 2024 Macro Update – NFE (nitrogen‑free extract) formula adjusted in energy density calculations.
- Turkish Ministry of Agriculture & Forestry – Drafted a 2025 sustainability framework for companion‑animal feeds.
Bottom line: expect to see fresh label language—“black soldier fly protein,” “carbon‑neutral production,” and “functional beta‑glucan”—on your next bag of dog food.
Grain‑Free vs Grain‑Inclusive: A Deep Dive into Canine Nutrition
2.1 Advantages of Grain‑Inclusive Formulas
- Complex Carbohydrates – Oats, brown rice and millet offer easily digestible, fibre‑rich energy.
- Steady Energy Supply – Ideal for sport and working dogs requiring long‑lasting fuel.
- Micronutrient Profile – Whole grains deliver B‑vitamins, magnesium and selenium.
2.2 Advantages of Grain‑Free Formulas
- Low Glycaemic Response – Pea protein, legume fibres and sweet potato moderate blood‑sugar spikes.
- Allergy Management – Beneficial for dogs sensitive to wheat gluten; can reduce pruritus and GI upset.
- Higher Animal‑Protein Load – Grain‑free recipes typically feature more meat by percentage.
2.3 The DCM Controversy {#dcm}
Between 2018‑2023, FDA logged dilated cardiomyopathy (DCM) cases linked to grain‑free diets. A 2024 report concludes it is not the grain absence per se but possible taurine deficiency and poor bioavailability that pose risk. Takeaway: whatever the label, ensure your dog food balances taurine, methionine and cystine.
Rising Protein Sources for 2025
| Protein Source | Environmental Impact | Digestibility (PDCAAS) | Market Share* |
|---|---|---|---|
| Black soldier fly larvae (BSFL) | Very low | 0.79 | 4 % |
| Basalt micro‑algae protein | Low | 0.91 | 1.2 % |
| Hydrolysed chicken | Moderate | 1.00 | 9 % |
| Lamb & goat | High | 0.94 | 13 % |
*Projected Turkish market share by end 2025.
Sustainable proteins are reshaping dog food. BSFL alone can slash carbon emissions by up to 85 %.
How to Read a Dog Food Label
4.1 The First‑Five Rule
The first five ingredients account for > 70 % of total weight. “Chicken,” “chicken meal,” and “hydrolysed chicken liver” in positions #1‑3 usually signal superior biologic value.
4.2 Calcium‑to‑Phosphorus Ratio {#ca‑p}
| Life Stage | Ideal Ca:P |
| Puppy | 1.2 : 1 – 1.4 : 1 |
| Adult | 1.1 : 1 – 1.3 : 1 |
| Senior | 1.0 : 1 – 1.2 : 1 |
Incorrect ratios spell long‑term skeletal and renal trouble.
4.3 What “Complete & Balanced” Really Means
The phrase must align with AAFCO or FEDIAF feeding trials or nutrient profiles. By June 2025 you should be looking for formulas compliant with FEDIAF Nutritional Guidelines for Complete and Complementary Pet Food (2025 edition).
Choosing the Right Dog Food: Step‑by‑Step HowTo {#howto}
- Assess Age & Activity – Puppy, adult, senior; high‑energy vs couch potato.
- Run a Vet Blood Panel – Creatinine, ALT, ALP, glucose; personalises feeding plan.
- Hypoallergenic Audit – Skin tests; note any elimination‑diet history.
- Set Macro Targets – Determine Protein‑Fat‑Carbohydrate percentages.
- Budget & Supply Chain – Monthly cost and domestic vs imported.
- Transition Protocol – 25 / 50 / 75 % over 3‑7 days.

FAQ – About Dog Food
Does grain-free dog food completely eliminate the risk of allergies?
No. Most allergic reactions are linked to the protein source (e.g., chicken, beef) or additives; grain/gluten is only a trigger in some cases.
What should I look for in cat / dog food to reduce the risk of DCM?
Pay attention to the balance of taurine, methionine, and cystine, and keep the legume/potato ratio below 35%. Schedule regular cardiac screenings with your veterinarian.
Is it safe to feed puppies food that contains grains?
AAFCO-approved “growth” complete and balanced grain-inclusive formulas meet puppies’ developmental needs; portion control remains important.
Do grain-inclusive foods cause dogs to gain weight faster?
Yes—if they create a calorie surplus. However, an active dog will use the complex carbohydrates in grain-inclusive food for energy.
Do insect-protein diets count as grain-free?
Most recipes contain no grains, but always check the label; some brands combine insect protein with oats.
What should I look for when choosing a tasty food for my picky dog?
High meat content (30 %+), hydrolyzed liver flavoring, and moist canned diets can boost palatability, but a veterinary check-up should come first.
What’s the difference between gluten-free and grain-free food?
Gluten-free products exclude wheat gluten but may contain grains like oats or rice; grain-free diets contain no grains at all.
Is the glycemic index of grain-free foods really lower?
Ingredients such as sweet potato and chickpeas raise blood sugar more slowly, yet the recipe’s total starch load is the key factor.
Do grain-inclusive foods make digestion harder?
Whole grains supply soluble fiber and generally cause no issues in healthy dogs. In irritable-bowel cases, fiber reduction may be needed.
Must functional (hypoallergenic) diets always be grain-free?
No. Some hypoallergenic formulas use hydrolyzed soy or rice and still contain grains; the goal is to reduce antigen size.
Should senior dogs eat grain-inclusive or grain-free food?
More critical than grains are phosphorus restriction and easily digestible proteins. A low-phosphorus grain-inclusive formula can work well.
Can grain-free food cause diarrhea?
Legume-heavy diets may lead to gas and diarrhea in some dogs; introduce the new food gradually and consider probiotic support.
Is grain-inclusive food advantageous for sporting / working dogs?
Complex carbohydrates supply sustained energy, and when paired with high fat/protein levels, grain-inclusive formulas can boost performance.
Which legumes are considered risky in grain-free diets?
Peas, lentils, and chickpeas have high lectin content that can reduce taurine absorption if overused; their share should stay below 35 %.
How long should the transition be when switching to grain-free food?
Follow the 7-day 25 %-50 %-75 % rule; for sensitive dogs, extend the transition to up to 14 days.
Is grain-inclusive food harmful for a dog that tested negative for grain allergy?
No. If the dog has no wheat-gluten reaction, a balanced grain-inclusive diet is perfectly acceptable.
Should grain-free food be preferred for dogs with kidney disease?
The priority is low phosphorus and controlled protein levels; whether the food is grain-free or grain-inclusive is secondary.
Is grain-free canned food more nutritious than dry grain-inclusive kibble?
Canned diets provide extra moisture that supports urinary health; overall nutrition depends on the specific formula and calorie density.
Are grain-inclusive foods risky for diabetic dogs?
Low-glycemic grains (oats, barley) given in controlled portions can fit diabetes management, but regular veterinary monitoring is essential.
Why are grain-free foods more expensive?
They often contain higher animal-protein levels, premium ingredients instead of legume/potato fillers, and incur greater marketing costs.
