A gardener applied black mulch that he said is natural and not dyed. Yet when it rains, the color attaches to my dog. Is it normal for undyed mulch to have color wash off?

1I suggest that most mulch is a brown colour and your black mulch is dyed.– kevinskio ♦Commented Dec 13, 2022 at 16:56

I work in the horticulture trade. All colored mulch—black, dark brown (chocolate), gold, red and (believe it or not) blue—is dyed. The only commonly available mulch that is not dyed is shredded bark and arborist wood chips.
Color leaches from wood mulch only if that mulch is dyed, so your landscaper is either misinformed or is mis-informing you. Theoretically, once the mulch thoroughly dries off it should stop leaching color, although I've known mulch to continue to leach onto concrete for several weeks.
