Biological Basis of Canine Nutrition

• Domesticated dogs show higher amylase activity
• Improved glucose tolerance through selective breeding
• Optimized protein utilization from different sources
• Increased efficiency in fat digestion

Digestive Physiology of Dogs

Detailed analyses of canine digestion provide important insights into digestive time and nutrient absorption: Digestive Phases and Duration:

• Gastric transit: 2-8 hours (depending on size)
• Small intestinal transit: 3-7 hours
• Large intestinal transit: 12-48 hours
• Total transit time: 17-63 hours

Protein Synthesis and Amino Acid Profiles

Essential Amino Acids for Dogs:

• Arginine: Important for immune function and wound healing
• Histidine: Supports hemoglobin formation
• Isoleucine: Muscle building and energy metabolism

Fatty Acid Metabolism and Immune System

Comprehensive analyses of fatty acid utilization in dogs examine the effects of different omega-3 and omega-6 fatty acids on health parameters.

• Omega-6 to omega-3 ratio: 5:1 to 10:1
• EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid): Coordinate individual dosage with your veterinarian

Carbohydrate Metabolism and Energy Supply

Carbohydrate Needs by Activity Level:

Types of Dog Food in Detail

Advantages of high-quality dry food:

• Long shelf life: 12-18 months with proper storage
• Portion control: Easy calorie control
• Nutrient stability: Vitamins remain stable for 15 months Disadvantages and Risks:
• Dehydration: Lower water intake
• Overprocessing: Loss of heat-sensitive nutrients
• Preservatives: Potential allergy triggers Health Benefits of Wet Food:
• Weight control: Greater satiety with fewer calories

BARF (Biologically Appropriate Raw Food) - Scientific Analysis

Veterinary research on raw diets shows both potential benefits and risks. A Dutch study examined 35 commercial BARF products and documented microbiological contamination (PMID: 29326391). The analysis identified bacterial and parasitic risks associated with raw feeding. BARF Benefits According to the Mueller Study:

• Natural nutrients: No industrial processing
• Individual adaptation: Customized nutrition possible
• Digestion: Smaller, firmer stool Risks and Concerns:
• Costs: 2-3 times more expensive than commercial food
• Time required: 45-60 minutes daily for preparation

Puppy Feeding (0-12 Months)

Veterinary specialist literature documents the optimal nutrient ratios for puppy growth. Veterinary nutrition guidelines emphasize the importance of adjusted calcium and protein levels, especially in large breeds.

• Calorie density: 3,500-4,500 kcal/kg for growth energy Feeding Frequency by Age:
• 6-12 weeks: 4 meals daily
• 3-6 months: 3 meals daily
• 6-12 months: 2 meals daily
• From 12 months: 1-2 meals daily

Senior Feeding (7+ Years)

Veterinary specialist literature documents age-related changes in senior dogs. Scientific review articles show that aging is associated with chronic inflammation, reduced muscle mass, and immune function (PMID: 38625530). Nutritional strategies for seniors include increased omega-3 intake and adapted protein supply.

Food safety studies show that older dogs need about 50% more protein than younger adult dogs to prevent age-related muscle loss (Top Companion Anim Med, 2008, PMID: 18656844). Protein intake should make up at least 25% of calories, with at least 7 g of protein per 100 kcal metabolizable energy.

Senior-Specific Nutrient Requirements:

• Omega-3: Double dose for joint health
• Antioxidants: Vitamin E, C, beta-carotene for cell protection

Research on antioxidant supplementation shows that increased dietary antioxidants (vitamin E, vitamin C, β-carotene) lead to improved cell protection and reduced DNA damage in dogs (J Anim Sci, 2024, PMID: 38828917). The maximum circulating vitamin E concentration is reached at around 1,000 IU/kg food.

Allergies and Food Intolerances

Veterinary allergy research documents the main allergens in food allergies. Clinical studies show that elimination diets with short-term glucocorticoid therapy can accelerate diagnosis (PMID: 31617265). Veterinary specialist literature identifies beef, dairy products, and wheat as the most common triggers. Most Common Food Allergens:

• Phase 1: 8-12 weeks single-protein diet
• Phase 2: Gradual reintroduction (one protein source per week)
• Phase 3: Identification of triggers

Overweight and Weight Management

Weight Reduction Protocol:

Gut Health and Microbiome

Veterinary research on gut health shows the central role of the microbiome. Scientific studies document that the canine gut microbiome regulates metabolism, protects against pathogens, and influences the immune system (PMID: 31993446). Veterinary studies confirm the influence of fiber, starch, and protein content on microbiome composition (PMID: 33653538). Optimal Gut Flora Composition:

• Diversity index: >3.5 for optimal health Prebiotic and Probiotic Effects:
• Probiotic cultures: high establishment rate in many dogs after 4 weeks

Skin and Coat Health

Skin/Coat-Optimizing Nutrients:

• Biotin, zinc (organically bound), vitamin E: Coordinate dosage individually with your veterinarian

• Last meal: 3-4 hours before bedtime
• Weight stability: clearly better control
• Energy level: More even throughout the day

Portion Sizes and Calorie Needs

Resting Energy Requirement (RER) Calculation:

• For dogs 2-45 kg: RER = 70 × (body weight kg)^0.75
• Simplified for 10-25 kg: RER = 30 × kg + 70
• Puppies: RER × 2.0-3.0 (depending on growth phase)
• Adults: RER × 1.6-2.0 (depending on activity)
• Seniors: RER × 1.4-1.6 (reduced metabolism) Activity Factors:
• Very low activity: RER × 1.2-1.4
• Low activity: RER × 1.4-1.6
• Moderate activity: RER × 1.6-1.8
• Very active: RER × 1.8-2.2
• Working dogs: RER × 2.0-4.0
