I am quite certain that some dogs have some form of ESP, and further more, I will go out on a limb and say that my dog is quite a bit smarter than some adults I know, certainly smarter than some frickin democrat green tard.
My Jack Russel Corgi mix is no Einstein. She’s got a strong herding instinct and a blank stare.
