Hi there
i am an ex ruc northern ireland dog handler and i passed my sia level 3 cp course last year. A year down the line i am still trying to get work as a cp dog handler in the middle east. The answer to you question is there are no regulations with dog handlers and the sia. It should mean you would think you would be more employable in the security industry but its a case of too few jobs and too many looking for them. I hope this helps you
