I don't care what the experts say, all of my dogs have loved being hugged. They hugged back, and they initiated hugs. Our 85 pound Airedale hugged my dad every time he returned from a business trip. She jumped up and down and would put her front paws around dad's neck.
Max and Teddy love hugs. Teddy is more of a voluntary submitter, gets into position and buries his head in us.
Max actively initiates hugs and will put his arms around my neck, rest his head on my shoulder. We hug many times a day.
