So why doesn't islam teach that animals (such a dogs) should not be tortured, set fire to, kicked, teased etc. Where is the love for all of God's creatures great and small?

My child has always been taught to respect others and animals too. Children that are taught compassion above all things are always wiser.

"The greatness of a nation and its moral progress can be judged by the way its animals are treated." Mahatma Ghandi
