Dog walking

I have loved animals my whole life and have always been around them. I have been looking into a career change. As I'm active and love walking, no matter the weather, so I thought why not do dog walking? I have personal experience with walking multiple dogs at a time, and I take water, treats, and a first aid kit on every walk. I know lots of dog friendly areas to walk. I have completed a level 3 in animal care award and I'm looking to expand on this. I will accept most dogs, but I will need to know their commands, temperament, if they're toy or food motivated, personality and how they are around children. I have my own dog duggee, who will be walked separately most of the time, but he is a friendly boy who gets along with other dogs and children. I work flexi time but I'm planning to try and ensure I have at least one set morning/lunchtime off every week to provide some consistency to my schedule.
