Mine is ok till it is 62 degrees. No shakes or nothin'. But at 62 degrees he starts shivering away, then he demands his coat. HE HAS A SPECIAL HOWL JUST FOR THAT. He is definitely my sons dog till he gets mad at him or my son is not home. Then he is mine.
Now if my sugar is off or I am upset, he knows and will not leave my side.
He will actually lay with his head on my leg, or walk beside me and whimper. Constantly looking up trying to make eye contact, till I get it started back under control.
He likes to roam if wife or kid tries to walk him,off leash outside. But if my sugar is high, he will walk with me no leash, constantly at 2 ft on my right, and never wander a bit, anywhere I walk to and all the way back in the house. Nobody trained him, he just knows and does.
He can tell if my sugar is getting too high or low, and when it is coming back under control before I can.
