I found Wynnie trembling today for no reason. She woke up normally and jumped up on the bed to enjoy some "rub a tummy time" with DW and me. Did her usual business outside and ate breakfast. Ninety minutes later as I was about to go outside, I found her sitting in the living room-trembling.
I picked her up and held her but the trembling continued. She seemed to settle down after a mile walk and some fetch time. I brushed her out but she still is needy. At the present time, she is lying down on my lap and resting. She has never exhibited this behavior before. Anyone have an explanation?
