Dogs are intelligent animals and
have been selectively bred for
centuries, to more then 400
different types of breeds, for
special jobs. These jobs require
many breeds to develop
characteristics for working alone.
Hence certain breeds are easier to
train than others, I.e. Doberman
Pinschers, German Shepherds,
Border Collies, Labrador
Retrievers and Golden Retrievers
are easier to train then Hound
dogs, Sledge dogs, terriers etc..
