I was born and raised in WA and have done plenty of hiking in UT, so I’m no stranger to snowy hikes. That being said, my Anchorage-raised cousin, his pug, and I enjoyed the hike (although I would absolutely love to see the falls without the snow). My only word of caution is that when the snow gets packed down and hard, it can be very slippery. Try walking on the of the trail in order to keep your footing. I would also highly recommend waterproof pants.
