Thank you for letting me know, I was unsure if that was something that needed to be done on a regular basis or not. I do need to find another groomer, which is going to be hard in my area. When I use to take him, I would it an chat while they did Gizmo, so I did not have to drop him off and come back later. The problem is I know I will have to drive little ways, and it doesn't make sense to drive home only to turn around and go back.
So for now I will continue to do it myself.
Have a good one!
