I agree. Many Dogs hate to be hugged, initially... some learn to tolerate it, others learn to like it.
1. My 65 lb. dog likes close contact, gentle caressing, careful ear scratching (inside the ear, also), light nose rubbing, scratching certain spots. Including the base of his tail.
2. He LOVES to have his belly rubbed - He will walk up to strangers, let them pet him, slowly sink down, then collapse in a "submissive posture" inviting a belly rub, stretching and moaning at just the right time for best compliance ...
3. He doesn't like to be hugged, but he does like me to 'hug' (?) his chest ... like a thunder shirt. He also likes me to bounce or push him gently against a wall or the bed, which I guess feels the same as the chest hug.
4. I think that tug of war is a show of affection (?); as opposed to Fetch, which is just a game to play. ???
