My dog loves us to scratch under her armpit. If she's laying on her side and you pet her side - she adjusts herself so her front leg is over your hand, to get the armpit scratch. She also expects a few kibble in her bed at bedtime. Also has to say goodbye to both daughters every school morning and watches/barks when their bus comes home. She definitely a habitual dog lol.
quizzickle - when my dog wants to see food on the counter, she does this completely vertical jump as the ears fly up. If somethings within reach - she'll do the jump but with a head lunge to grab the food morsel.
