New member here and new GSD owner. My GSD has started circling around the living room the past few nights. Always has his nose to the floor like he is following a scent trail. If you distract him with a toy, treat or speaking to him. He will stop for a few minutes then start again sometimes in the opposite direction. He is only created a for few hours a day in the mornings. Perfectly healthy normal dog. Any suggestions are appreciated. Thanks in advance, Todd
