Why was Caesar Milan sued?

Answer 1

On May 5, 2006, Flody Suarez, a television producer for the TV series 8 Simple Rules, filed a lawsuit against Millan, claiming that his Labrador retriever had been seriously injured while at Millan's training facility during an exercise routine on a treadmill. National Geographic Channel released a statement that Millan was not present at the facility at the time of the alleged incident. Millan has also claimed that Suarez's personal dog trainer was with the dog, Gator, while it was at the Dog Psychology Center and that he did not charge Suarez or Suarez' dog trainer for use of the Dog Psychology Center facilities. Millan had allowed Suarez' trainer to bring Gator to the center as a favor. A hearing to discuss the suit was cancelled, since a settlement (the terms of which were not made public) was reached on March 29, 2007.
