According to the Wikipedia article on Animal welfare in Nazi Germany:

• At the end of the 19th century, kosher butchering and animal vivisection were the main concerns of the German animal welfare movement. The Nazis adopted these concerns as part of their political platform.

• A law imposing total ban on animal vivisection was enacted on August 16, 1933 by Hermann Göring. He announced an end to the "unbearable torture and suffering in animal experiments" and said that those who "still think they can continue to treat animals as inanimate property" will be sent to concentration camps.

• Göring also banned commercial animal trapping and imposed severe restrictions on hunting. He prohibited boiling of lobsters and crabs. In one incident, he sent a fisherman to a concentration camp for cutting up a bait frog.

• On November 24, 1933, Nazi Germany enacted another law called Reichstierschutzgesetz (Reich Animal Protection Act), for protection of animals.This law listed many prohibitions against the use of animals, including their use for filmmaking and other public events causing pain or damage to health, feeding fowls forcefully and tearing out the thighs of living frogs.

This makes me wonder if the Nazis were consistent in their animal rights concerns or if their concern about animal rights was mainly a way to make Jews look bad.

Nazi Germany supported Francoist Spain and had a large number of French people under their rule. Did they attack and slander the cultural practices of Spanish Bullfighting and French Foie Gras production?
