Hi everyone. Kenzo is 9 months old, and my trainer tells me to keep him on puppy food til he is 1 yo. I have read some posts, and lots of folks here switched to adult food at 4 months. Am I too late?. Have I screwed up with his development?. He is on solid gold wolf cub. I'm planning barking at the moon, or wolf king of solid gold as adult food. Which one should I use? Barking at the moon is for active dogs, grain-free and 41% protein. Since he is a very young dog ( still a baby though), is it ok to use such a food with high protein content? Please tell me something. I''m so confused. Thanks
