Lots of folks who live in a city have outside dogs. There's gotta be a fenced yard, and a dog house. I've not hever had to deal with severe winter conditons, but I guess you could easily insulate a dog house, and maybe rig some sort of little electric heater. Hot pad, maybe. Dunno.
A solo dog does okay as long as daily attention is given. And I do mean daily.
Hunting dogs tend to be high energy critters. Better give some thought to that part of the deal. And, being high energy, they're very active and quite often rather noisy.
I think I'd talk to some of your local folks who are in similar physical situations to what you have about "just" dogs in general.
Galfriend allergic to dogs? Hmmm. Might trade for one that's not allergic.
