Here's my latest problem. When we first got the dog we had a regular garbage can (open at the top) which of course she got into. So I ended up buying one of those "simple human" ones with a lid that stays closed. That worked for several months. Well the other day when I was gone she figured out how to tip it over and get the lid open and she made a big mess of course. And since then she's done it every day. Is there some kind of garbage can I can buy that she won't get into? Do I have to put the garbage can outside when I leave? How would I train her to stay out of the garbage? Or is the best answer to get a crate and work on crate training her?
