Key Features

• 26LB bag: A single large bag supplies multiple feedings suitable for adult large-breed households, reducing shopping frequency.
• Trout protein: Fish-based protein provides a distinct animal protein option for rotation and can be easier on some dogs compared with common land proteins.
• Prebiotics and probiotics: Added digestive support helps maintain a healthy gut and can improve stool quality over time.
• Heart health blend: Balanced Omega-3 and Omega-6 fatty acids with L-Carnitine, taurine, choline chloride and DL Methionine support cardiovascular function and overall metabolism.
• AAFCO-complete: Formulated to meet AAFCO guidelines for all life stages, making it suitable for growth and maintenance when recommended by a vet.

Who It's For
