Hey sawnie,heres a thought. Take some tyvec three foot wide by 9 foot long.
Sew it togeter at the end leaving a channel in the tyvec for a piece of 2.2 zing it to pass through.
When folded up its a welcome mat for your hammock that is three by three,and weighs very little.
When unfolded,im seeing little squares of velcro holding it together in this mode,it pops out to be a two sided tent with a tyvec floor,you could get creative and fashion doors if you like that open ,and close for wind block/venting.
Run you cordage through the channel ,now you have a ridge line that you can tie to the trees your hanging from ,this puts the dog house right where you could reach out ,and pet the poodle.
A piece of pad in the floor for winter with your unused while sleepin jacket over the top ,or inside covering the pooch in colder weather.
You could spray the thing so that it repels ticks and mosquitos .
This could work for any size friend just custom size it.
Lumber yards have this type of material that wraps the board shipments that come in. They will give it to you for free to keep from filling up those expensive to have dumpsters.
