Electric dryer I assume? Exhausting a gas dry into the house could be, well, problematic.
My parent's have vented their electric dryer into their laundry room during the winter for years. They get their "deflectors" from Mom's dresser.
Dad cuts the leg off of a pair of her pantyhose and hose clamps it to the dryer vent hose. When it get's "linty" he replaces it.
