D.O.G. ? That a Chemdog cross?
From Leafly:
Black Dog by Humboldt Seed Organization is a weighty mixture of two northern California favorites,
Blackberry Kush and Emerald Headband. This medium-sized plant expresses dark, nearly black leaves that give way to sticky, dense buds. Its aroma is a mixture of grape, berries, and oil while the effects tend to be relaxing with just a touch of cerebral stimulation. Black Dog has a rapid flowering time of 48-55 days.
I ran it a few years ago and loved it. Both
@thenotsoesoteric and I have used it in successful crosses, and he gifted me the seeds this time. I don't know if it's made or available anymore.
