Many people are very tough with dogs but tolerant with cats

Maybe because unrestricted (for example, no collars) dogs could easily hurt people.

I fear dogs because I've been chased by one wild dog for 1 km.

I don't like dogs because dogs  are meat-eaters.

回复 @巨大八爪鱼：Cats do also eat meat. (But mainly fish)

回复 @啊啊是谁都对：Dogs do surely have more possibility to hurt people
