Our dog breed of preference is the Alaskan Malamute. When we lived in Seattle our Malamutes loved the weather so we seldom had need for "extra cooling" for them. Then a job change later, we moved to Texas! Here in Austin we have a bit more temperate weather than DFW or Houston, but it's Tejas still! So, we realized that while being inside in the Air Conditioning and having a dog door was a requirement for the dogs, we also realized that they might want/need more cooling... so, we found a big powerful fan that moves a LOT of air! This fan sits on the ground which will allow the dog to lay in front of it and cool down more. Problem is, the dogs want to be where you are, and the fan is NOISY! Having it run 24/7 isn't an option. So we were having to turn the fan on/off/on/off/on/off (any dog owners who have upgraded to a dog door know JUST how demanding a dog can be once they learn how to operate you as their remove control!) got old FAST!
After far too long/eventually I realized, this problem has been solved! I just need to adapt it to our needs! So, I ordered a 110v relay, picked up some supplies at the hardware and art supplies store, rummaged around through my electronics, and built a floor mat 110v relay powered Dog Fan switch!
