Kery,
Welcome to GO Corgi! We have had numerous discussions on crates and pens and gates for our corgis - check out past threads for good info.
when I leave my Girls (Emma & Chloe) I either gate them in the kitchen (also where their crate is) or on nice days I leave them on our gated deck (they have shade & dog house there too) But my Girls are 7 years and 10 mths and I live in an area that I don't need to worry about stray dogs or strangers.
Hope to hear lots of corgi stories and see lots of pictures of the new puppy!
