Low shed on a collie

Low shed in this horrible heat in western PA.
This girl dad has been shedding for a couple weeks but she still has some.
I am showing you the Rale instrument and how to pull up on dogs fur starting at bottom and brush from bottom of body to top letting fur fall a little at time while brushing yo get undercoat out..
You do not need to brush hard. Just go with easy strokes as I am in video.
Sadie hates being brushed period but I wanted to use her as my model as it's easy to see her fur coming out and how I let it fall with each stroke of brush.
