The Impact of Diet on Canine Behaviour: What the Science Says

Recent research published in the Journal of Veterinary Behaviour (2023) reveals a compelling connection between what goes into your dog’s bowl and their behaviour. According to the British Veterinary Association’s latest studies, dietary choices can influence everything from anxiety levels to learning ability and social interaction.
The Science Behind Food and Behaviour
The University of Cambridge’s Animal Behaviour Unit (2023) has identified three key pathways through which diet affects caninebehaviour:
1. Neurotransmitter Production
Research shows that dietary components directly influence:
● Serotonin levels (mood regulation)
● Dopamine production (reward and pleasure)
● GABA synthesis (anxiety control)
● Norepinephrine balance (alertness)
2. Blood Sugar Regulation
Studies from the Royal Veterinary College demonstrate:
● Stable glucose levels support consistent behaviour
● Energy crashes can trigger aggression
● Balanced nutrition improves focus
● Meal timing affects temperament
3. Gut-Brain Communication
The latest research in Veterinary Science Quarterly reveals:
● 70% of mood-regulating hormones originate in the gut
● Digestive health impacts emotional stability
● Microbiome diversity affects behaviour
● Inflammation influences mood
Key Nutritional Factors Affecting Behaviour
According to the Journal of Animal Nutrition (2023), these components significantly impact canine behaviour:
Essential Nutrients
- Proteins
● Amino acid balance for mood regulation
● Tryptophan for serotonin production
● Tyrosine for dopamine synthesis
● Complete protein sources for brain health
- Fatty Acids Studies show crucial roles for:
● Omega-3s in cognitive function
● DHA in brain development
● EPA in reducing inflammation
● Balanced fatty acid ratios
- B Vitamins Research indicates importance for:
● Stress management
● Energy metabolism
● Neural function
● Cognitive performance
Behavioural Issues Linked to Diet
The Canine Behaviour Research Institute identifies these connections:
Common Problems
- Anxiety and Stress
● Nutrient deficiencies
● Gut inflammation
● Neurotransmitter disruption
- Hyperactivity
● Carbohydrate quality
● Protein quality
● Meal timing
- Aggression
● Low tryptophan levels
● Nutritional imbalances
● Blood sugar crashes
● Inflammation
Evidence-Based Solutions
Recent clinical trials published in Veterinary Medicine Today show:
Dietary Interventions
- Protein Selection
● High-quality sources
● Complete amino acid profiles
● Novel proteins (including insect protein)
● Appropriate protein levels
- Feeding Schedule
● Consistent timing
● Appropriate portions
● Balanced nutrients
● Strategic distribution
