I've heard Katz on WAMC a couple of times. He's a writer, not a dog trainer. The real problem I see is that people call in asking for advice- and he gives it. WAMC also has a regular guest , Sue Sternberg, who is a dog trainer and behaviorist and who, I think, gives very good answers to people with dog problems- any dog not any specific breed. I think the listeners are used to calling her for reliable info, and assume they get it from Katz as well. WAMC ought to direct the Katz shows to stories and writing, not advice.
