Working with dogs

Hi Guys,
As its the new year, iv been thinking about how I could change my career to work with dogs, but im stuck. Id like to learn to be a dog trainer, but dont really know where to start, and cannot do any full time courses as we really need both our full time wages. Wondering if any of you guys work full time with dogs, how you got into it, and what you do ??

I work full time as a pet sitter/dog walker so technically I work with a variety of animals, cats, horses, rabbits, guinea pigs, hamsters, mice, sheep, fish, birds, etc etc but its mainly dogs. I love my job

Wow that sounds fab!
