premium dog food

When I tried to switch to premium dog food such as Blue Buffalo, Taste of Wild and 4 health my Collies had loose stool. (not good with a long hair dog)

I tried to mix with there old dog food to change them over but the loose stool would not go away.

The Collies can process all kinds of human food without having any problems except for lobster and hot dogs.

I feed Pedigree dry with a can of Pedigree over the top. They get whatever I'm having for supper, small portion without any problems.

Any one else have problems with premium dog food?

How long did you go through this switch? I found that many times, when changing the type or brand of food, it can take a few days for their digestive system to get used to the change and they'll have loose stool for those days.
