More: Chevy alerts me when my blood pressure is higher than normal. He learned this skill all on his own, I had to learn his signs to me, and he's never been wrong. I have an aortic dissection with an aneurysm and keeping my blood pressure low is critical to my survival day to day. So his intuitiveness is a life safe for me. I am his 3rd human and got hims when he was just 8-9 months old. He knows he found his forever home. I kinda of saved his life and he certainly has saved mine with his skill for sensing my blood pressure.
