My dogs are outside all day everyday. Rain, shine, heat, snow. I think because they are exposed to it, they acclimate very well. They do come in at night because I can't stand to listen to them barking at the nightlife, BUT they have a cool place to sleep and my furnace is set down at 60 degrees at night. Many times I have had my irish setter almost solid icicles, but still excited to stay outside and play with me. My lab stayed outside also, but she was pretty old and arthritic, so she slept in the insulated doghouse most of the day.
My dogs as well stay outside all the time. At one time I built floor less houses to placed atop a mound of dirt that I would hollow a nest into then fill with straw and pine or spruce sprigs. I would even go so far as to staple a piece of denim or canvas over the doorway.
Now I make these "lavish" dog mansions with a small sleeping quarters, a landing and a "3 sides enclosed" shaded area large enough for them to stretch out in.
It's all an exercise in futility. They dig holes to lay in summer and sleep on top their houses through -40 -50 blizzards.
But at least the bleeding hearts that come to "visit" me recognize my efforts to accommodate my dogs "needs".
God bless my dogs. They are so cool...... ......and tough.... .....and hardworking.... ....and happy....and friendly....and....and...and...
LOL. I'm having a late lunch so I'm taking time to chat.... and kinda rambling to eh.
