The senior dog experienced an unspecified but extremely traumatic experience with his previous owner, causing authorities to step in and take Buster out of the home.
Mr. Farrell, who had initially only agreed to take in Buster, eventually fell in love with him and took him in.
Because of his traumatic experience, Buster suffers from a significant generalized anxiety disorder, as well as problems forming perceptions of unidentified men.
It was obvious that the dog would need a lot of help to deal with his problems, but Farrell was not discouraged.
In fact, Farrell went to great lengths to help Buster overcome his trust issues.
