Wow! I would agree with you that it is probably at least partly due to diet, but you just described a fairly typical young Border Collie behavior. They have to learn to turn off and settle down sometimes. That’s why so many of them end up in shelters, unfortunately. He needs a food with no food dyes, no artificial preservatives, and no added sugars. Border Collies, as a breed, were developed on grains, so unless yours have additional problems, you probably won’t have to go grain free. My first suggestion for food would be NutriSource. It is easy to transition to and it isn’t really expensive. See about getting him in an obedience class and working him in the house so he learns that the house is a place for more orderly behavior. And playing games that take mental work are really good for BCs, so teach him to search for hidden toys and teach him the names of his toys to start with.
