I was looking at books on dog behavior and happened to look at "The Hidden Lives of Dogs" by Elizabeth Marshall Thomas. It is one of the worst books I have ever read, because it completely stands up for animal abuse.
Her twelve million dogs run around the neighborhood, unfixed and crossing busy urban highways
. She even lets a dog who killed her puppies give birth again! One fourth of the puppies her dogs have had have died.
She let them attack an innocent yorkie pup! No effort is made to make them part of the family, they are just poorly socialized research subjects. I wish people like her could never own animals again, period.
