Excellent Heater For Dog Pen
Your review: We have 2 security dogs that are kept out side throughout the year. I purchased this heater in fall 2014 and in the winter months it helps keep the dog pen temperature at least at 50 degrees and also keeps the dog's water buckets from freezing as well.
Pros: Safe to use around pets if mounted high enough where they cannot reach it. You can direct the heat down towards the ground.
