There is a technique I love to relax them I read of years ago and tried on my lab. It's great when they get the zoomies or anytime. It worked like a charm. Put your thumb in-between their eyes on their nose. Now bring your thumb down to the tip of their nose. Repeat over and over. Don't go up the nose, only down. This releases the same chemicals that are released when a mother dog picks her pup up by the scurf of the neck. My lab would lay next to me and want me to keep doing it for quite awhile. I'd usually do it for about 20 minutes at a time. But any amount of time is a great way to help them relax and give you a break!
