Another one from my sister

I am not sure where she gets these but some are pretty good.

A little girl asked her Mom, "Mom, may I take the dog for a walk around
the block?" Mom replies, "No, because she is in heat."

"What's that mean?" asked the child.

"Go ask your father. I think he's in the garage."

The little girl goes to the garage and says, "Dad, may I take Belle for
a walk around the block? I asked Mom, but she said the dog was in heat,
and to come to you."

Dad said, "Bring Belle over here." He took a rag, soaked it with
gasoline, and scrubbed the dog's backside with it to disguise the scent,
and said "OK, you can go now, but keep Belle on the leash and only go
one time round the block.."

The little girl left and returned a few minutes later with no dog on the
leash. Surprised, Dad asked, "Where's Belle?"

( YOU'RE GONNA LOVE THIS!!!!!!!!! )

The little girl said, "She ran out of gas about halfway down the block,
so another dog is pushing her home."
