Here's Boomer
Season 2
Boomer was a cute stray dog of mixed breeding who wandered around the country getting involved with people and their problems, including a deaf girl believed to be mentally disabled by her parents, a son neglected by his workaholic father, a private detective guarding valuable jewels, and a band of dognappers. Later in the series, Boomer was able to talk to the viewing audience, so we could know what Boomer was "feeling" at any given moment.
