I have stuck to a twice-daily feeding schedule ever since Graysee was a puppy. 6:00 AM, and 6:00 PM, with times varying within an hour, depending upon what time I actually get out of bed, get home, etc. Any additional meals would result in her resembling a football with legs! She will eat anything, any time, with few exceptions. Lately, I've been trying to break her from asking for a treat every time she asks to go out and potty; it's been hard, and I've certainly spoiled her. She IS a little overweight, even for her larger size, so it's going to be a long, hard road getting her "untrained".
