i have heard of cases like that. he is behaving normally, he is eating and is his funny little self. I felt his stomach and it seems normal, not hardened or bloated and he regularly does a number two as well. we had him vet checked only a couple of weeks back and his teeth etc was all in perfect shape. since then i haven't noticed any differences at all.
he only does it at night time when everyone is in bed, nothing has changed in their routine at all. i am going to leave his evening walks a bit later from now on to see if it tires him out a bit more towards bed time.
