Harvest Moon 64 Cheats

Such A Healthy Dog!
I don't know if this will help much, but here goes:
To get your dog to like you more, feed it every day, then do your chores (it also helps to take your dog with you WHILE you do your chores). When you are about to leave pick up your dog (or if you already had it picked up, continue what you were doing) and head to the town/mountains/or wherever you go to normally. Do this all year long and your dog will like you. You can miss a couple of days, but not much. If your dog likes you, you have a better chance of winning the Dog Race.
***Note: Only feeding your dog does not make him like you. Also, if you feed it Cake/Cookies/Pie, it will appreciate you, I have found!
