He has existed for centuries as a herding dog in England and Scotland
Personality and Behavior
He's strong, agile, extremely energetic and possesses a lot of stamina
He's very intelligent and loves working
If he isn't mentally and physically stimulated he will start behaving badly (he isn't a good choice if you cannot give him lots of exercise everyday)
He's loyal and gentle (great with children!)
He likes barking and can be quite noisy
He's very easy to train. He learns commands very quickly.
He sheds profusely! You will find a lot of hair in your home - stuck to your couch, carpets and clothes - and to just about everything else. You will be vacuuming regularly.
Grooming / Maintenance
His short coat only needs to be brushed occasionally. However, because it sheds profusely you may find yourself brushing it a couple of times a week, or even daily, to reduce the hair in your home (what you remove with a brush doesn't end up on the couch!).
