A dog that is well-trained is quite amazing and is often a welcome part of any household. At times, however, they go beyond the standard training of knowing how to sit, lay down and stay and they learn some rather epic tricks. That is the case with Nana, a border collie that is one of the smartest dogs I have ever seen!
It’s not unusual to think that a border collie would be able to do all of these tricks. Many dogs are smart but it has been clearly shown that border collies are among some of the most intelligent dogs on the planet!
