Maizee hates the cold. I usually have a sweater on her even when she's indoors because she is almost constantly shivering. She has alopecia so that doesn't help, but I never let her go outside without a sweater on. She doesn't seem to mind. I dont use boots; they don't seem to help much because she usually shakes them off. I just dig through the snow, if there is snow, and make her a path to go potty. With the sweaters, even if they hate them to start, they usually get used to them. Never hurts to try!
