#Think that dot is not allways colliding pad so you can't do this, when dot 
collides it should change the sign of it's velocity:
         dot.dir = -dot.dir
# Or
         dot.speed = -dot.speed

# The same for the left pad
         dot.dir = -dot.dir
# Or
         dot.speed = -dot.speed

I see you haven't take in account the y-axis movement, it works the same way but 
you should have a 2-component speed, so, the class dot will look like that:
class dot:
	x = 317.5
	y = 207.5
	width = 15
	height = 15
	speedx = +1
	speedy = +1


Greets, Marcos.
