Review on 🔥 300W Electric Dog House Heater with a Durable Cord and 3 Adjustable Fan Settings for Pet Enclosures and Dog Houses by Wendy Bengtson

I built a small kennel for a medium sized dog with insulation and a rubber flap door. This heater works, if you can call it that, but produces little heat. When I have it on medium settings it can keep the inside temp about 10-15 degrees warmer than the outside temp. So if it's 25 degrees outside, it can be 40 or so inside. Low settings do almost nothing. Also, it makes a slight buzz when you turn it on, and it took my dog a few days to get used to it enough to get inside.
