Aired: 1988-93 Family Channel
DAD: Hank Katts (Jesse Collins) / Single 
DAD’S JOB: Cop
KIDS: Stevie (Andrew Bednarski) / nephew
WHERE’S MOM?: Maggie Davenport (Cali Timmins) died in Season I
STAND-IN "MOM": Rin Tin Tin?
How on earth did Rin Tin Tin survive Fort Apache and make it into modern day Anytown? Probably the same way David Carradine’s character made it into the spin-off Kung Fu series.
Uncle Hank was a K-9 dog handler who wound up taking care of nephew Stevie after Stevie’s mom died in one episode. Of course, Stevie wound up on the business end of a lot of police busts during the run of the series.
I’ll bet you’re wondering how come THIS show qualifies, and the ORIGINAL Rin Tin Tin DOESN’T? Well, in the original, the little boy Rusty winds up being generally adopted by the WHOLE troop stationed at Ft. Apache. Thus, there’s no one fighting to take on that singular role of TV Single Dad in that original show.
