The present invention provides dose counter for displaying a count indication of the number or quantity of doses dispensed from or remaining in a container associated, in use, with the dose counter, comprising an indicator member comprising dose indicia and a priming indicator for prompting a user to carry out one or more priming actuations of the container. The priming indicator is initially arranged to at least partially overly the indicator member to thereby at least partially obscure viewing of the dose indicia of the indicator member until the one or more priming actuations of the container have been completed. The priming indicator is movable after the one or more priming actuations have been completed into a disposition where it no longer obscures viewing of the dose indicia of the indicator member. The invention also provides a dispensing apparatus comprising the dose counter.
