A collie is probably THE most intelligent dog in the world!!!
They are dogs that crave stimulation and exercise!!
So, if its on it own during the day, make sure you leave it with plenty to occupy its brain.
The appearance of collies really doesnt appeak to me, but this breed astounds me with how quick it can learn and just how much it can learn!
They are great at agility, so think about flyball or agility classes when its older!
