🍖 Why Nutrition Matters

Healthy muscle doesn't come from exercise alone.
Nutrition provides the building blocks needed to support lean muscle, recovery and overall wellbeing.
A complete, balanced diet appropriate for your dog's age and activity level should always be the foundation.
Owners of active bully breeds often pay close attention to:
🥩 High-quality protein
🐟 Healthy fats

Together with regular exercise, these help support healthy muscle condition.

🦴 Supporting Muscle Throughout Life

Nutritional needs change as dogs age.
🐶 Puppies
Growing bully breeds need balanced nutrition to support healthy development without encouraging excessive growth.
🏃 Active Adults
Regular exercise places greater demands on muscles.
Good nutrition helps support normal muscle maintenance and recovery after activity.
👴 Senior Dogs
As dogs age, they naturally lose muscle, a process known as sarcopenia.
Maintaining regular activity, appropriate body weight and balanced nutrition becomes increasingly important.
Research continues to investigate ingredients such as HMB for supporting normal muscle metabolism in ageing dogs.

Following illness or injury, always follow your veterinarian's advice.
Once appropriate, nutrition and controlled rehabilitation may help support the recovery process.
