Hi Labman,

You've talked previously about switching from puppy to adult dog food early on to prevent HD in dogs. My rough collie is now about 4 months old. Should I swtich to adult dog food now or wait for another couple of months?

Thanks in advance.

I would switch over as soon as your current bag of puppy chow gets low. Keep mixing a little more adult chow in over a week until the puppy chow is all gone, and you are feeding all adult chow. I some times just dump the old food on top of the new and each feeding is richer in the new.
