Shep

Shep is a wise male  collie, a very loyal ranch dog, and always a help to the horses in times of trouble. He is often the voice of reason for Teeny and Angora, and, to illustrate a moral or lesson, often relates stories to Teeny (the episodes are actually flashbacks to previous events). His owner is Bailey, and Shep has been with him since puphood. In the series, Shep is very wise and friendly. He can be cautious, for an example in  Molly and Chilly, he follows them into the wood as he does not think they are safe. Shep is also in charge of keeping the horses safe.
