I will admit the thought of a Husky that doesnt like the cold weather made me giggle. I do not think hypothyroidism runs in huskies, but you could have it checked. The desire to lay in the sun, or get warm when there isnt a obvious reason for it, is one of the signs. Or maybe she just prefers to be inside where there is a good couch.. lol.
As far as going in the house- considering its only during the day, and I am sure you already had to checked to see if she has a urinary infection ( UTI), maybe you can just keep an eye on her and try to catch her in the act. Watch for leaving the room you are in. If you are gone when this happens- I would either crate her, or contain her like in a room that is small. Maybe if you are gone, you could come home at lunch time to let her out for a little run. The pooping in the house is the strange one. Does she have enough time after she eats to go outside with you there to priase her when she does go? We went through a " spitful" act with femka for a little while. If I took one of the other dogs- she would go find their bowl and go near it.. lol.. My dogs eat in seperate rooms, so just simply shutting the door of the room of the dog I took, solved the problem. ..
