Dog Trainer
What you'd actually do
The work is running training classes or one-to-one sessions, teaching commands and good manners, tackling problem behaviours and coaching owners on how to keep it up at home. Patience, consistency and an understanding of how dogs learn matter, as does the people side, since you are really training the owners as much as the dogs.
Many trainers are self-employed, working evenings and weekends to fit around owners, with income built up from classes and private clients over time. It is active, outdoor and people-facing work, and building a reputation takes patience and good results.
There are no strict legal qualifications, but a recognised dog-training or canine-behaviour course, insurance and first aid are expected by most clients. Experience with dogs is essential, and an enhanced DBS check may be needed if you work with children or vulnerable people.
