I give my dog Pedigree dog food every day. He used to get Iams's but Pedigree was cheaper and seemed to give him a healthier body and happier personality.
He was constantly itching when I gave him Iams, so when I switched to Pedigree, I had hoped it would help. Not only did his coat grow thicker and more shiny, but he also was more active, more playful, and less hungry throughout the day.
Pedigree gave him more energy and he was more excited to be fed his breakfast and dinner.
