Ditto on thanks for informative post by rsmit02.
Choco our dominant male, exhibits similar behaviors. Assertively licks Scooby, cleaning his ears, penis, etc... Especially likes to lick wounds. This worked out well when Scooby developed a large sore, more like a whole from his IV treatments after 2nd head trauma. Scooby could not reach very well but Vet suggested after we moved to Tokyo from Bangkok, to allow wound to air and dogs to lick. It healed after a stuborn infection. Scooby's ears tend to get dirty and Choco's licking helps with the cleaning. Seems Scooby prefers to the drops and gauze from Vet. Choco also helps clean the gunk out of Scooby's eyes. Scooby tries to clean himself by licking paws and rubbing but no match for Choco's direct tongue. Choco's ears are very clean, and he also does good job of cleaning his own eyes via licking paws.
If I have a scratch, rash, Choco likes to lick as well.
Scooby likes todo the walk by quick lick flips. Both dogs do it to each other often as they pass.
Often when someone returns Choco and Scooby like to give a quick lick as part of the greeting, welcome back along with the excited dancing about.
Post shower is also a favorite time for a lick, guessing in part to welcome us back, but also fondness for dampness. They like to lick condensation from cold objects as well.
Choco at the dog run(park) will often try licking other dogs, thought he was being friendly, but as rsmit02 enlightened me, more of a dominant behaviour.
Scooby often likes to do a licking session feet, hands, arms for several minutes often just before a nap. Saw a tv program on a Japan polar bear who also loved to lick his handler, referred to it as "skinship" helped to relieve stress. Guessing this is similar for Scooby.
Appreciate hearing about others licking behaviors and better understanding.
