Well, we DON'T have yard access, and while Seamus gets fed only at certain times, we try to keep Kirby's
food bowl full and down for him all the time. However, we do this in hopes that he
will eat more than usual! Samoyed have a bad, bad habit of NOT eating enough food and at this point in time Kirby's habit has caused him to lose weight.
I personally see nothing wrong with leaving food out. It was common practise where I lived in the country. My family always kept our dog's food bowl full outside so that Dudley could come and eat when he wanted; he spent a lot of time with my grandfather working or in the woods chasing squirrels or killing snakes, so it was much easier to do this than keep him on a feeding schedule.
I would say just watch their weight, since you and I both know little dogs are prone to put on some pounds.
