I have an Oster Grooming Set in a Box, and used to "try" to groom my guys myself. I have since given up on that
and there's been some months since I groomed them, taking them to a Pro now.
However, when I do get the notion to give them a Brushing, they still look at me very suspiciously when I get the Box out, but, calm down when they see it's just the Brush in my hand. The do NOT like the Clippers.
