The Rough Collie was first bred in Great Britain respectively Ireland as a sheep
dog. Later these beautiful dogs were bred for their looks and a more or less show
type breed was developed. Today's specialists for herding sheep are Border Collies.
Queen Victoria was a Collie "fan" who increased the breed's popularity outside the
community of sheperds. In the 20th century the "Lassie" movies were a boost for
the spread of the Rough Collie.
Today there are two types of Collies, the British and the US-American type. The colours are sable, tricolour and blue merle. Typical traits are the white collar, white feet and the white tip at the end of the tail.
No, you don't! There are different types of coat qualities, some are denser, some are longer but on average it will do to brush your dog once every two to four weeks. You should only keep an eye on the very soft fur behind the ears, it can tend to tangle up. Collies shed their coat twice a year.
Collies are very sensitive and alert, thus they notice every noise. Your dog will "tell you" that there is something going on until you tell him it's okay. Apart from that Collies have a wide range of noises, almost like a language to express their minds. If you leave your Collie to himself for longer periods of time he may well get bored, look for something to do and start barking at everyone non stop. It's up to the owner to prevent this from becoming a bad habit.
On rainy days the mud may splash up to the belly but the good thing is that the Collie coat will clean itself. Leave the dog in a "dirt zone" of your house for a while to let it dry. After some time the mud will fall out as dust and the Collie is clean again. If you like, you may bathe the Collie (for shows etc.) but it's not really necessary.
