I used Merrick dog food for our Mastiff Titan from July 2025 to October 2025, completing a 4 month feeding period focused on controlled nutrition for giant breeds. From the start, the transition was smooth, his appetite excellent, and he accepted the ingredients immediately. By the second month, his growth tracked positively, coat condition improved, and digestive wellness was consistent. By September, his development was optimal, health markers outstanding, and premium nutrition clearly effective. By October, his muscle strength advanced, energy stayed balanced, and overall condition was excellent. This 4-month review shows Merrick supports giant breed growth and long-term wellness effectively. ✨
