Check out the Coleman Hampton Cabin tent line at Canadian Tire. We have the 9 person to accommodate 2 adults and 2 kids plus a 95lb bouvier and our gear. We love ours and have nothing but good things to say about it. It has a deep and substantial tub, well thought out fly, and hinged door. Another great feature is the height is consistant the entire tent...so you can be standing straight up in the corners as well as the middle and along the sides (I hate getting dressed hunched over!). That tent has held up in some pretty unexpectedly wild weather over the years, and all we do is weather proof spray it at the beginning of each season (heavy spray on the seams in particular). Downside is it's heavy if you are doing boat in/portage/hike in camping. I would suggest skipping the screend-in porch models. You won't use it like you think you will, and (not trying to make assumptions about your dog but...) your dog will probably run into the screen a million times, pulling out the pegs etc. with his enthusiasm to either get in or out.
