Thanks to Keith for this information:
Katherine can be seen on “Woof! It’s A Dog Life” with Matthew Margolis on your local PBS station at various intervals over the next few weeks.
She appears in Program 208 (the 8th show of Season 2):
“TV star Katie Heigl is having trouble with her two Schnauzers, Gus and Romeo, who are simply too aggressive. Uncle Matty helps diagnose the duo’s behaviour problems, and then demonstrates effective corrective techniques”
To find out scheduling information check out your local PBS station.
Be sure to set your VCR early as Katherine appears at the beginning of the show!
