My breeder always told me to leave food out at all times for him. When he was a pup, I'd leave dry food out and feed him a 1 tablespoon of canned lamb and rice 3 times a day, and then after a week I narrowed it down to 1 teaspoon.. now I just keep dry food out.
I'm not sure if this is good. Which one would be better, I wonder.. a scheduled eating time or just to let him eat however much he wants when he's hungry.
