Why did the pepole who made scooby doo make him a talking dog?

I guess because it fit best! I mean, how boring would it be if Scooby didn't talk? All he would do is stand around and bark. I'm glad they made him a talking dog, it's so much 更多 fun that way! ;D

theres been Mr ed a talking horse, but he didnt want to walk on two legs, so mans best freind, who listens anyway!!!!!!;-]

To make him cuter <3 <3 <3 and funnier <3 <3 <3

Because talking 动物 are awesome!
