Though exact genetics are unknown, Chemdawg or Chem Dog is attributed as a cross between OG Kush and Sour Diesel for a full-bodied hybrid. Chemdawg has a similar terpene profile to Sour Diesel with a pungent and fuel-like aroma. Not recommended for inexperienced patients because of the strong body high, Chemdawg is good for chronic stress, anxiety, migraines and PTSD.
