Quick Start: What You Can Do TODAY
Do you want to begin optimal dog nutrition immediately? This quick-start guide shows you how to implement concrete improvements within the next 24-48 hours.
Step 1 (Next 24 hours): Calculate calorie needs
Scientifically based RER method (Resting Energy Requirement):
The Ohio State University Veterinary Medical Center (College of Veterinary Medicine Nutrition Resources) recommends this precise formula for calculating energy requirements:
RER formula: Body weight in kg^0.75 × 70 = resting requirement in kcal
Example calculation for a 25 kg dog:
- 25^0.75 = 11.18
- 11.18 × 70 = 782 kcal (resting requirement)
Multiplication factors by activity:
- Weight loss: 1.0 × RER = 782 kcal
- Neutered, low activity: 1.6 × RER = 1,251 kcal
- Intact, moderately active: 1.8 × RER = 1,408 kcal
- Light work (1-3h/day): 2.0 × RER = 1,564 kcal
- Moderate work (3-5h/day): 3.0 × RER = 2,346 kcal
- Puppy 1-4 months: 3.0 × RER
- Puppy 4-12 months: 2.0 × RER
Step 2 (Tonight): Check feeding amount
How to calculate the right portion:
- Determine calorie needs (see Step 1)
- Read the food energy value (listed on the packaging: "kcal per 100g")
- Calculate the portion: Daily requirement ÷ kcal per 100g × 100 = grams per day
Practical example:
- Dog needs 1,251 kcal/day
- Food contains 350 kcal per 100g
- Calculation: 1,251 ÷ 350 × 100 = 357g per day
- Split into 2 meals: 178g in the morning + 179g in the evening
Step 3 (This week): Check the ingredient list
Quality checklist for dog food:
✅ First ingredient = named protein (e.g. "chicken", "salmon", "beef")
❌ Not: "meat meal", "animal by-products" (vague terms)
❌ Not: Grain as the first ingredient
✅ Clearly declared additives: "Vitamin E", "Omega-3 from salmon oil"
❌ Not: "flavourings", "plant by-products" (unclear)
✅ Preservation: Vitamin E, Vitamin C (natural)
❌ Not: BHA, BHT, Ethoxyquin (artificial)
Recommendation: If you want to cook for your dog yourself, consult a veterinary nutritionist for balanced recipes.
Interactive feeding calculator: How to use it correctly
What you need:
- Your dog's current weight (not ideal weight!)
- Age in months
- Neuter status (neutered/intact)
- Activity level (hours of active exercise per day)
- Health status (healthy/overweight/underweight/senior)
Interpreting the results:
| Result | Meaning | Adjustment |
|---|---|---|
| Calorie requirement | Total energy per day | Basis for feeding amount |
| Dry food amount | Grams at Ø 350 kcal/100g | Adjust to your food (check packaging) |
| Wet food amount | Grams at Ø 100 kcal/100g | Higher amount due to water content |
| Meal distribution | 2-3 portions | Adults 2x, puppies/seniors 3x |
Important: Calculators provide starting points; observe your dog's body condition:
- Ribs easily felt (not visible): Ideal
Problem 1: Dog is not eating
Veterinary decision protocol:
Go to the vet IMMEDIATELY if:
- ❗ No food intake for 2+ days
- ❗ Additional symptoms: vomiting, diarrhoea, lethargy
- ❗ Bloated/tense abdomen
- ❗ Diabetic dog refuses a meal
- ❗ Puppy is not eating (they cannot fast as long as adults)
If the dog is otherwise healthy (1-2 days of loss of appetite):
Step 1: Improve the food
- Warm the food to body temperature (37°C) to intensify smell
- Add topper: 1 tbsp cottage cheese, cooked chicken, tuna (in its own juice)
Step 2: Optimise the feeding environment
- Quiet location without distractions
- Raised bowl for seniors (reduces joint strain)
- 15-minute rule: Offer bowl → remove after 15 min (no constant access)
Step 3: Rule out medical causes
- Dental problems: Check gums for redness/swelling
- Stress: New environment, changes in the household?
- Medication: Side effects possible (contact veterinarian)
Problem 2: Dog is too thin (underweight)
Weight gain protocol:
Step 1: Increase calorie needs
- Calculate current requirement (RER formula)
- Example: 1,251 kcal → 1,501 kcal/day
Step 2: Energy-dense food
- More frequent meals: 3-4x daily instead of 2x (improves absorption)
Step 3: Monitoring
- Weigh weekly at the same time
- Check body condition score every 2 weeks
- Goal: ribs palpable but not visible
Problem 3: Dog is too heavy (overweight)
Scientifically based weight reduction programme:
Calorie requirement for weight loss:
Macronutrient adjustment:
Practical implementation (example: 25 kg dog, 1,251 kcal/day):
- Maximum treat calories: 125 kcal
- Option 1: 25g dried chicken (≈125 kcal)
- Option 2: 125g carrots (≈50 kcal) + 15g liver treats (≈75 kcal)
- Option 3: 40g apple (≈20 kcal) + 20g cottage cheese (≈25 kcal) + 10g training treats (≈50 kcal)
Problem 4: Dog has digestive problems (diarrhoea/vomiting)
Veterinary bland diet protocol:
Phase 1 (Day 1-2): Fasting
- 12-24 hours no food (adult dogs)
- Water ALWAYS available (avoid dehydration)
- Puppies and seniors: fast only 6-12h
Phase 2 (Day 2-3): Introduce bland diet
- Cooked chicken (without skin) + white rice (2:1 ratio)
- Small portions: 4-6 meals per day
Phase 3 (Day 4-7): Gradual return
When to see a vet:
- Diarrhoea lasting longer than 48 hours
- Blood in stool or vomit
- Fever above 39.5°C
- Apathy, dehydration
Checklist: Nutrition quick check
✅ Calorie needs calculated (RER formula applied)
✅ Feeding amount adjusted (to activity level and body condition)
✅ Ingredient list checked (named protein as first ingredient)
✅ Feeding times set (2x daily for adults, fixed times)
✅ Fresh water (change daily, 50-60ml per kg body weight)
✅ Body condition monitored (ribs palpable, not visible)
Nutrient requirements: What dogs really need
Current veterinary research on nutrient requirements in dogs documents modern nutritional standards for optimal canine health (PMID: 38625522). Essential macronutrients (case study): Scientifically based protein requirements:
- Adult dogs: 18-25g high-quality protein per 1000 kcal
- Puppies: 28-35g protein per 1000 kcal up to 12 months
- Seniors: 22-28g easily digestible protein per 1000 kcal
- Active dogs: 25-32g protein per 1000 kcal
Biological value: Understanding protein quality
Scientific analyses on protein quality and bioavailability in dog food document the biological value of different protein sources. Biological value indicates how efficiently a dog's body can convert dietary protein into body protein.
Table 6: Protein source comparison table (comprehensive)
| Protein source | Biological value | Digestibility | Price/kg | Allergen potential | Special nutrients | Recommended for |
|---|
Legend:
- € = inexpensive (<€5/kg)
- €€ = moderate (€5-10/kg)
- €€€ = expensive (€10-15/kg)
- €€€€ = very expensive (€15-25/kg)
- €€€€€ = extremely expensive (>€25/kg)
Allergen potential based on clinical data:
Protein sources by biological value:
Highest quality (90-100 BV):
- Whole egg: 100 (reference protein) - contains all essential amino acids in the optimal ratio
- Salmon: 95 (rich in omega-3) - additionally provides EPA/DHA for brain and joints
Medium quality (70-89 BV):
- Lamb: 85 (for sensitive dogs) - low allergen potential, rich in CLA
- Turkey: 82 (low fat) - high tryptophan content (natural calming agent)
- Pork: 78 (palatable) - good source of thiamine, must ALWAYS be cooked (Aujeszky virus)
Plant proteins (60-75 BV):
- Lentils: 74 (rich in fibre) - prebiotic effect, high iron content
- Chickpeas: 71 (supports digestion) - good complement to animal proteins
- Quinoa: 68 (gluten-free) - complete amino acid profile (rare in plants!)
Modern fatty acid science
Clinical studies on omega-3 fatty acid supplementation in dogs with chronic diseases show significant improvements (PMID: 20187817). Optimal fatty acid supply:
- Omega-6:Omega-3 ratio: 5:1 to 10:1 (optimal)
- Coat quality: Clear improvement with an optimal ratio
- Skin problems: Clear reduction in allergic reactions
- Joint health: Fewer inflammatory markers
- Cognitive function: Better learning ability observed

Dry food vs. wet food: The scientific evidence
Dental health comparison:
- Plaque formation: Tends to be higher with wet food
- Saliva pH: Higher with dry food (healthier)
- Bad breath: Lower sulphur concentrations with dry food
- Bacterial population: More health-promoting bacteria (Pasteurella, Capnocytophaga) with dry food
Table 2: Detailed nutrient comparison
| Nutrient | Dry food (per 100g) | Wet food (per 100g) | AAFCO recommendation |
|---|---|---|---|
| Energy | 350-400 kcal | 80-120 kcal | Varies by age |
Scientific evaluation of dry food:
Advantages:
- Dental health: Significantly less tartar due to abrasion effect

- Omega-3: EPA/DHA for anti-inflammatory effect Advanced kidney insufficiency (stage 3-4):
- Potassium: Supplementation often necessary
- Antioxidants: Vitamin E, C for kidney protection
Probiotics and microbiome
A comprehensive review on the gut microbiome in dogs and cats and the influence of nutrition documents the role of probiotics and prebiotics (PMID: 33653538). A controlled clinical study with 36 dogs showed that probiotics can significantly shorten recovery time in acute diarrhoea (1.3 vs. 2.2 days, p=0.04) (PMID: 20137007): Scientifically proven probiotic strains:
- Bifidobacterium animalis: Immune system support
- Enterococcus faecium: Diarrhoea prevention
- Bacillus subtilis: Spore form for stability Optimal probiotic feeding recommendation:
- Colony-forming units: 1-10 billion CFU per day
- Multi-strain formulas: 3-5 different strains
- Prebiotics: FOS, inulin as "food" for probiotics
- Duration of use: At least 8 weeks for microbiome build-up
Joint supplementation

- Activity: 30 minutes of rest after feeding One-meal system (adults only):
- Time: 17:00-19:00 (optimal for digestion)
- Portion size: Total daily ration
- Risks: Increased risk of gastric torsion in large breeds
Water supply: Often overlooked
Veterinary literature documents the importance of hydration for health and organ function: Optimal water supply:
- Requirement: 50-60ml per kg body weight daily
- Quality: Fresh water changed daily
- Temperature: Room temperature (15-20°C optimal)
- Access: Available 24/7, except before anaesthesia Dehydration warning signs:
- Skin tent test: >2 seconds to return
- Mucous membranes: Dry or sticky
- Urine concentration: Dark yellow or orange
- Behaviour: Lethargy, loss of appetite
BARF Nutrition: The complete safety guide
BARF (Biologically Appropriate Raw Feeding) requires thorough knowledge of nutrient balance, hygiene standards, and potential risks. The study by Schmidt et al. (PMID: 30110340) shows significant microbiome differences between BARF and commercial ready-made diets.
Step-by-step BARF protocol
Week 1-2: Preparation and planning
- Veterinary examination: Check blood count, organ function
- Nutrient calculation: Online calculator or nutritionist
- Equipment: Freezer, scales, separate cutting boards
Week 3-4: Gradual transition
Bone safety protocol
SAFE bones (under supervision):
- Chicken necks: Soft, easy to digest, for small dogs
- Chicken wings: Cartilaginous, low splinter risk
- Veal ribs: Soft enough for medium-sized dogs
- Beef marrow bones: Only as chew items (do not eat!)
- Lamb ribs: Suitable for medium to large dogs
DANGEROUS bones (NEVER feed!):
- ❌ Cooked bones: Dangerous splintering
- ❌ Cooked poultry bones: Extremely prone to splintering
- ❌ Weight-bearing bones: Femur, humerus - too hard (tooth fracture!)
- ❌ Raw pork bones: Aujeszky virus risk
- ❌ Raw game bones: Parasite risk
Bone feeding rules:
- Always supervise: NEVER leave alone
- Adjust size: Bone larger than the mouth
- Never when too hungry: Risk of gulping
- Introduce slowly: Start with 1-2x per week
- Monitor stool: Too much bone = constipation
Parasite prevention by freezing
WHO/FAO freezing protocol:
- -20°C for 7 days: Kills most parasites
- -10°C for 21 days: Alternative for a weaker freezer
- Special cases: Trichinella in game meat -25°C for 10 days
High-risk meat (always freeze):
- Game meat: Deer, roe deer, wild boar (trichinosis risk)
- Fish (freshwater): Trout, pike (tapeworms)
- Pork: Always freeze (Aujeszky, Trichinella)
Bacterial safety
Hygiene checklist:
- Separate work surfaces: For dog BARF only
- Gloves: When handling raw meat
- Immediate cooling: <4°C within 2 hours
- No cross-contamination: Keep separate from human food
Thawing protocol:
- Refrigerator: Overnight at 2-4°C (safest method)
- Cold water: In a sealed bag, change water every 30 min
- NEVER: At room temperature (bacterial growth!)

The 10 most critical nutrition mistakes
Veterinary literature documents common feeding mistakes by dog owners and their health effects. Critical mistakes and effects:
- Overfeeding (very common):
- Consequence: Many dogs are overweight
- Solution: Accurate calorie counting and portion control
- Irregular feeding times (common):
- Consequence: Digestive problems, stress
- Solution: Establish a fixed feeding routine
- Too many treats (frequent mistake):
- Consequence: Nutrient imbalances, weight gain
- Incorrect food transition (common):
- Consequence: Diarrhoea, digestive upset
- Solution: Gradual transition over 7-10 days
- Insufficient quality control (common):
- Consequence: Nutrient deficiencies, contamination
- Solution: Choose high-quality, tested food
Toxic foods: Updated list
Veterinary toxicology literature documents toxic foods for dogs based on clinical poisoning cases and experimental data. Highly toxic (life-threatening):
- Chocolate: Theobromine (50-100mg/kg toxic)
- Grapes/raisins: Unknown toxin (already dangerous at 10-20g/kg)
- Onions/garlic: Allyl propyl disulfide (5g/kg toxic)
- Xylitol: Hypoglycaemia (0.1g/kg dangerous) Moderately toxic (requires monitoring):
- Avocado: Persin (large amounts problematic)
