need your opinion on this plan
I have this giant tank where I store dry firewood and I have been wanting to convert it into a super-insulated dog house. My dogs prefer to be outside and absolutely hate it inside. I am working on fencing a 5 acres area for my dogs and would like to build them a really nice house for shelter.
I was thinking that I could build a dog house large enough for all four dogs and then fill every crevice with insulation. I will wire it for light and thermometer so I know what the temperature is. Is this a good idea? I am attaching a picture of this tank.
