Hello,
I'm afraid i have to agree with Jodi, Nicole, People whisperer, gr8dame, jacksmom, and all the rest who are for dogs being indoors. I don't want to reiterate all the points made, but just to give a small example:
our next-door neighbours rottie is kept out all year round and just 2 weeks ago a snake bit him and if it hadn't been for my mom who just happened to be in our garden and saw the snake and then a few minutes later realized that he was drooling too much and unsteady on his feet, he would have died. It was 6AM. He also gets very sick during winter (he has a huge dog house also, and a big garden and access to his food and water and a thick blanket), but he's always shaking so badly that at times i sit with him under the rain to keep him company.
As winter is pouring with rain half the time i cant' see how you'd be able to spend much time with him, and that'll be very hard on him being away from his loved ones. It's great though that you take him places with you, that's a plus, but really, think about moving him indoors, at least into the kitchen but not the rest of the house if your hubby is THAT uncomfortable with him being indoors. Just a thought. Ta.
