In Pokémon HeartGold, Houndoom can be found in the Burned Tower in Ecruteak City. Specifically, it appears in the lower levels of the tower, typically during the night. Additionally, you can catch a Houndoom by evolving a Houndour, which can be found in the Routes around Johto, though it's more rare. Remember to check the time of day, as some Pokémon only appear at certain times!
