Absaloutly they DO.
If you have an abused dog (i mean beaten etc) they owner appears, they either cower,growl,whine etc. No love there. or they cower and have a slight wag (as in i want to come and love you, but scared) this dog wants to love but is scared to for fear of being beaten.
and then theres the PTers dogs who all seem to be MAD about us,lol whole but wiggles, kisses, etc dog's that go OTT loving.
My dog loves
