Islam didn't said that, they are just crazy Persian Shia.

 

Well said

As long as this thread name is Islam and Dogs, there is another story tells about a man walking in the desert and he was very thirsty, then he found a well and he get down to the well to drink, after that he saw a thirsty dog licking the sand from the thirst. When he saw that, he remembered how he was so thirsty so he get down again and bring some water to the dog and the man entered the heaven for this act.

 

I like thats story
