I was looking in the newspaper and..........................?

I saw a Chihuahua puppy for sell and it said............ CHIHUAHUA Puppies for sale, 4 weeks old, call between 9am-9pm. Is he a BYB? I am not going to buy a puppy but i was just curious if i can report him? Coz i though that a puppy should be with its mom until 8-12 weeks. BTW he is in Las Vegas and i am in Utah can i still report him??? Thnx
