When people think about improving their dog’s behaviour, they often focus on routines, consistency, and dog training. While these are essential, diet plays a much bigger role than many owners realise. I’ve seen firsthand how what goes into a dog’s bowl can directly affect focus, energy levels, and emotional regulation, especially for families living busy lives in Melbourne.

A poor-quality diet can contribute to hyperactivity, anxiety, digestive discomfort, skin irritation and more. Highly processed foods, artificial colours, and excessive sugars and salts may cause energy spikes followed by crashes, making dog training sessions far more challenging. I often notice that dogs struggling to settle or concentrate during lessons improve significantly once their nutrition is addressed.

Protein quality is one of the biggest factors influencing behaviour. Dogs need adequate, easily digestible protein to support brain function and muscle development. Diets that lack quality protein can lead to lethargy or frustration, both of which can show up as unwanted behaviours. Balanced fats are also vital, particularly omega-3 fatty acids, which support cognitive health and emotional balance. I always encourage owners to view food as a foundation, not an afterthought.

Gut health or a healthy gut barrier function is another key piece of the puzzle. Around 70% of a dog’s immune system is linked to their gut, and there’s a strong connection between gut health and mood. Dogs experiencing digestive discomfort may appear irritable, restless, or withdrawn. When combined with consistent dog training, a diet that supports gut health can make learning calmer and more enjoyable for everyone involved.

I recommend Lifewise dry food in combination with

• Big Dog raw patties
• Cooked root vegetables
• Tinned Springwater tuna or cooked Bassa fillet
• Pre and Pro Biotic

I exclude:

• Wheats, grains and cereals if dry food is already in the dog food bowl.

Treats are also worth considering. Many owners rely on treats during dog training, but not all treats are created equal. High-sugar or low-quality treats can undo the benefits of a good main diet. I recommend choosing natural, low-ingredient options that support learning without overstimulating your dog. I buy the following at Animal World of Boronia:

• Prime 100 rolls
• Freeze dried or dehydrated chicken/ fish
• Beef ears with fur on
• air dried roo ribs

Living in Melbourne, I know how tempting it can be to search for “dog training near me” when behaviour issues arise. While professional guidance is important, behaviour change is far more effective when nutrition and dog training work together. I’ve worked with many dogs across Melbourne where dietary changes made the training process smoother and more rewarding.

If you’re looking to improve your dog’s behaviour holistically, consider reviewing both their food and your training approach, you can check out our website and contact us through there for guidance.

By fuelling your dog’s body properly and supporting them with thoughtful dog training, you’re setting them up for long-term success and wellbeing.
