Today after running errands I came home to find my 7yo Shepherd Mix cowering in the corner. Typically he runs to greet us. I made sure he hadn’t gotten into anything then I let him out while unloading groceries, typically he enjoys running around the farm but today he hopped into the back of my SUV and refused to budge. As my truck was in a shady spot I let him be with the hatch and windows open while I mowed. Now several hours later he is still in the back of my truck. He has been offered water which he drank and we let his Golden Retriever best bud out who he was happy to see but still refused to budge. Typically he is a “Velcro” dog and stays right with us, especially my daughter. This behavior is very out of character and has me concerned .
