Have you noticed changes in your dog's behaviour lately – perhaps increased anxiety, digestive issues, or mood swings? Many Australian dog owners don’t realise these seemingly unrelated symptoms might share a common source: the fascinating connection between their pet’s gut and brain health.
Understanding the Gut-Brain Connection in Dogs
The relationship between your dog’s digestive system and brain is more profound than you might think. This intricate communication network, known as the gut-brain axis, plays a crucial role in everything from your dog’s emotional wellbeing to their physical health. When this system is out of balance, it can lead to a range of issues that affect both behaviour and digestion.
How Gut Health Affects Your Dog’s Mood
Your dog’s gut does much more than just digest food – it’s actually a powerful mood regulator. The digestive system produces important neurotransmitters like serotonin, dopamine, and GABA, which influence your dog’s emotional state and behaviour. When gut health is compromised, you might notice your furry friend becoming more anxious, reactive, or showing signs of stress.
Think of your dog’s gut as their second brain. This complex system not only processes food but also communicates directly with their nervous system, influencing everything from stress responses to learning ability. Recent research has shown that probiotics can help reduce anxiety and aggression in dogs by creating a more balanced gut environment. Specific strains, such as Lactiplantibacillus plantarum PS128, have been shown to reduce separation anxiety and aggressive behaviour in dogs.

The Power of Probiotics for Canine Wellbeing
Probiotics are beneficial bacteria that support your dog’s gut health, but their benefits extend far beyond digestion. These microscopic helpers work to:
- Maintain a healthy balance of gut bacteria
- Support immune system function
- Produce essential nutrients and neurotransmitters
- Help manage stress and anxiety levels
- Improve overall digestive health
One particularly interesting discovery is how specific probiotic strains can help reduce separation anxiety and aggressive behaviour in dogs. This connection between gut bacteria and behaviour has opened new doors for managing common behavioural issues through gut health support. Learn more from this veterinary article.
Signs Your Dog Might Need Probiotic Support
Watch for these indicators that your dog’s gut-brain axis might need attention:
- Increased anxiety or stress behaviours
- Digestive issues like diarrhoea or constipation
- Changes in appetite
- Mood swings or unusual aggression
- Poor sleep patterns
- Reduced interest in play or social interaction
The Role of Diet in Supporting Gut-Brain Health
While probiotics play a vital role in gut health, they work best as part of a comprehensive approach to nutrition. Including fibre-rich foods in your dog’s diet can help support their gut microbiome. Vegetables like carrots, pumpkin, and broccoli aren’t just healthy treats – they provide essential nutrients that help beneficial bacteria thrive.
These dietary fibres produce compounds called short-chain fatty acids (SCFAs), which help strengthen your dog’s immune system and support brain health. SCFAs also have anti-inflammatory properties and play a role in regulating the blood-brain barrier and microglial function. It’s a perfect example of how proper nutrition can influence both physical and mental wellbeing. For more on this, see this dietary balance article.
Practical Steps for Supporting Your Dog’s Gut-Brain Health
1. Dietary Considerations
- Introduce fibre-rich foods gradually
- Ensure a balanced, high-quality diet
- Avoid sudden dietary changes that could upset the gut
- Consider adding probiotic-rich foods when appropriate
2. Lifestyle Factors
- Maintain regular exercise routines
- Reduce environmental stressors where possible
- Establish consistent feeding schedules
- Provide mental stimulation through play and training
3. Monitoring and Management
- Keep track of behaviour changes
- Note any digestive issues
- Observe stress triggers
- Document responses to dietary adjustments
Supporting Senior Dogs
Older dogs often need extra support for their gut-brain health. As dogs age, their digestive system becomes more sensitive, and they may experience more anxiety or behavioural changes. Regular probiotic supplementation can help senior dogs maintain better digestive health and emotional balance.

The Science Behind Probiotic Benefits
Research has shown that specific probiotic strains can significantly impact dog behaviour by influencing the gut-brain axis. These beneficial bacteria help produce GABA, a neurotransmitter that regulates anxiety and stress responses. For example, Lactiplantibacillus plantarum PS128 and GABA-producing strains like LP815 have shown promising results in reducing anxiety and aggression in dogs.
When choosing a probiotic supplement, look for products specifically formulated for dogs, as they contain the most appropriate strains and dosages. A helpful resource is this Cornell Vet article.
Safety and Implementation
While probiotics are generally safe for dogs, it’s important to introduce them gradually. Start with a lower dose and increase it slowly while monitoring your dog’s response. Some dogs may experience mild digestive changes initially as their system adjusts to the new beneficial bacteria.
Working with Your Vet
Always consult your veterinarian before starting any new supplement regimen. They can help:
- Determine the most appropriate probiotic strains for your dog
- Recommend the correct dosage based on size and needs
- Monitor progress and adjust as needed
- Address any specific health concerns
Looking Forward
Understanding the gut-brain connection opens new possibilities for supporting our dogs’ overall wellbeing. By taking a holistic approach that considers both physical and mental health, we can help our furry friends lead happier, healthier lives. Remember, every dog is unique, so what works for one might need adjustment for another.
The connection between gut health and behaviour in dogs continues to be an exciting area of research, offering new insights into how we can better support our canine companions. By paying attention to this crucial relationship, we can help our dogs maintain better physical and emotional balance throughout their lives.
