Both our corgs have definitely been "personal space" critters, especially Mouse, who wouldn't even snuggle with us. Rose likes a cuddle, but it is on her terms - she cuddles when she wants to. Although she can generally be sweet-talked around...
With other animals, Rose likes to keep a certain distance - the little warning lip-lift appears when any cat or dog, even those she knows well, gets too close. Although a cat that is sleeping is certain to get a nose-poke in the back. Perverse creature.....
We had a very elderly dacsy that we took in - she dealt with the cats stealing the best place in front of the fire thing by backing up to them and shoving them off the mat. Knew damn well which end would get hurt on a stand-off!
