There's a line I love in my dogumentary film, "Hey, Mister, What Kind of Dog is That." (Find it in the rail to the right.)

It came from Stan the Biscuit Man, as he sat on a bench in Riverside Park and tossed treats to his, shall we say, full-figured, mutt, Louie.

"He's like living with a cartoon character," Stan said.

My dog Ace isn't quite as animated as Louie, but he is cartoon character. His likeness appears in a dog safety coloring book put together by Karma Dogs, the therapy dog organization of which he is a part. (A video of Ace's therapy dog experience can be found in the rail, too)

On Saturday, Ace will be returning to the organization's reading program at the Baltimore County Public Library in Towson.

And on Sunday, at 1 p.m., he'll be making his first public appearance since our return to Baltimore. Along with some other Karma Dogs, several of which were used as models for the book, he'll be appearing at Dogma, 3600 Boston St. in Canton.

"We will go over some dog safety for a bit and then kids can get pawtographs from the dogs featured in the coloring book," said Kelly Gould, Karma Dogs founder.

Illustrated by Baltimore artists, "Dirk's Guide to Dog Safety" is aimed at reducing the thousands of children injured by dogs every year by better understanding how to behave around them, Gould said.
