Pleased that your health has stabilised :)
IMHO, dogs sense when we're emotionally or physically upset/ out of balance.
My dogs are very tuned in to me, particularly when I have a relapse with my ongoing health problems and behave much like your dog, ie, following me
everywhere and watching me closely, even when I don't want to be watched :D
If you have a good relationship with a dog, as you clearly do, then they display what I can only describe as a sixth sense.
