Hey all- fairly newbie pup owner- we bought our first NTU this summer and have enjoyed it so far- I have searched a bit in the forums but want a direct answer to a few things. We want to camp a few more weekends in late Sept/October and our pup does not have a furnace. We will be at a campground and I think a small ceramic heater will be fine (temps are in in the 50s at nite here in CT now) My SO thinks it too cold. She also said NO to the heater thinking it is dangerous!?!!! Lol So, I need you to all back me up here. Can I make it safer? A tile or something underneath? Keep it off the floor away from the dog?
