Is he on limited diet for a reason? Like, having a sensitivity?
I have 8 dogs, I've switched their diet when they first came to me. I wait 2-6 weeks to switch the diet, depending on how long the dog takes to settle in. When I switch, I do it over 2 weeks. I do not switch them immediately unless it's a truly bad food, such as Alpo or Pedigree.
When they are still settling into the home, they can have digestive upsets. You don't want to mask a food intolerance or assume the food is no good.
Switching foods, slowly, should not cause issues unless they dog has a sensitivity. You may notice a chance in activity level or coat which is a cue they need a different food. I have one dog that gets a very dry coat when fed anything with rice, even the highest quality food.
