equine embrace
A.k.a. "horse hug", this immensely-pleasurable (well, if you're into regularly getting "up close 'n' personal" wif half a ton of hard-muscled mammal, at least!) activity involves happily wrapping your arms around the neck of your favorite large four-legged friend and tucking your head contentedly up under his jaw and throat; if he is accustomed to doing this and is in a fairly good mood, your large buddy will often respond in kind, gently tilting his head downwards to softly squeeze you between his chin and chest.
Equine embraces can indeed be extremely satisfying and rewarding; one just needs to remember to always check his clothing for loose hairs and other unwanted "organic adornments" afterwards, to avoid spreading said "residues" to undesirable locations, such as furniture, curtains, bed-clothes, etc.
