Our beloved pet dog: the Collie.

The story of the Collie seems like a fairy tale. It was a simple Scottish shepherd dog, until one fine day, the Queen of England fell in love with its elegance and decided to take it home. From there, the Collie became so famous that it became one of the most beloved dogs in the world. As far as we know, there are four main kinds of collie:
Bearded collie
>> Collie barbudo (PT-BR).
Border collie
Rough collie
>> Collie de pelo longo (PT-BR).
Smooth collie
>> Collie de pelo curto (PT-BR).
