I would check his weight. I had one that did the digging down thing all the time, She wasn't eating and her muscles started to waste, It wnet on for a couple of seasons so I didn't hibernate her. i took to the vet the first season, she had bloods and poo samples all clear. I could just about get her to eat if I got her up and put her under a lamp inside and warmed her up. She had to be in a box so that she couldn't leave the lamp, then she would eat a little bit, but as soon as she had the opportnity she would dig back down.

Eventually her weight got low enough for the vet to diagnose anorexia. She was fitted with a tube and I tube fed her back up to weight. Whilst I was tube feeding her she started to take and interest in life again and even food. That was about two years ago and she is as right as rain now eith the same behaviour as the other Hermanns and the same zest for life before it all happened.
I have no idea to this day what triggered this or why she came good with tube feeding but it worked! She is now a normal weight for her size and she trundles around like a good n!!!
