Feeding & use

Feed daily as a complete diet, adjusting portions based on your dog's weight, activity level, and body condition. Follow the feeding guide printed on the bag and transition gradually from your previous food over 7–10 days.

Always provide fresh water, and consult your veterinarian if you have questions about your dog's specific needs.
