I too have heard Moslems say that dogs are evil.

All of Allah's creatures are just that. They originate from the same source. Pigs are filthy, etc. But they too are on this planet.. There are wild pigs in many part of the world. We are forbidden to eat them.  But those pigs are still part of life.

It is hard to comprehend that aspect of the natural world are considered "evil." Science and knowledge of the natural world shows how cosmically interdependent al llife creatures are. That brilliance comes form The Creator.

Recenly there was a show on why some rhinos had msteriously been killed. As many many know, they are highly enddangered. It was a mystery. They  found out that these young males were killing them. This normally does not happen in the wild. But these males were the few left from human mass killings (culling) of elephants. These elephants did not have older makes to teach them to be elephants. When they moved some older bulls into the area. The younger males stopped killing. There are many, many examples of the delicate, masterful ecosystem is all intertwined.

Hating a whole group of animals seems rather to go with emotion than with logic.
