hello...i\'ve been waiting to see if anybody might have a straightforward solution but nothing so far...so i\'ll put in my two cents worth.

I\'ve had quite a few tervs over the years and they mostly live outdoors where they have the choice of spacious quarters (new 10X12 and 10X20 manufactured sheds) with complete protection from the elements and a hard floor or outdoor sleeping in the open or under a medium roof with a dirt floor or a low roof with a dirt floor.  None of the dogs ever sleeps in the pleasant large dry commodious pre-manufactured weatherproof  sheds that i bought and set up. Their preference on average nights is to sleep in the open in a shaped 4 to 6 inch depression that they dig that generally has their hindquarters lower than their shoulders in a gentle slope that sort of fits and supports their body form.   In hot or wet weather they prefer cool damp shade under a 3 to 4 foot roof that \'hides\' them where they again dig a shaped depression that conforms to and supports their body.  I have the impression that the cool damp earth is soothing and also shields soft parts from insects. The tervs who are parturient with new puppies prefer a low roof of 12 to 18 inches heavily shaded and concealed.  None of them ever seem to prefer the nice human grade dwelling that i set up for them at considerable effort and expense (even when the air conditioner is running inside!)

i don\'t know your circumstances but 2 things came to mind

1) go to jefferspet.com and order up a large black rubber feed tub in the 30 inch range, then go to the local feed store and buy a 50 lb bag of corn and lay down a 3 inch bed of corn in the tub for doggie to sleep on (or maybe 4 inch or 5 inch).  Doggie might ignore it. Or more likely he will dig in the corn initially and there will be corn everywhere for the first few weeks until the novelty wears off...or he might love it because it gives him the soft conforming shape he is trying to dig into the floor.

2) get some 2 X 4s and a sheet of light plywood and build a 3 X6 roof shelter 24 to 30 inches above the floor for doggie to hide beneath and sleep under.....having this roofed space to sleep under (thus concealing him from predators and enemies) might relieve his anxiety and let him get a full night\'s sleep.

...or it could all be wasted effort....but...my two cents worth.....B
