A collapsible and transportable dolly including first and second rigid base portions hingedly secured together at a central location. First and second pairs of wheels secure to underside locations associated with the base portions. First and second substantially rectangular and frame shaped end supports secure in upwardly extending fashion to opposite end locations of the hingedly connected base portions and first and second pairs of top brackets secure in interconnecting and hinged fashion between the end supports, and such that associated angled bracket portions extend from end locations of each of the top brackets and telescopically engaging the end supports. In this fashion, the dolly is converted from a use to a folded storage/transport position by folding the base portions upwardly about the central hinged connection, concurrent with inwardly and downwardly folding the top brackets concurrent with telescoping the angled brackets along end support channels.
