The term 'Dog Salmon' is used to refer to two species of salmon, the Humpback Salmon (Oncorhynchus gorbuscha) and the Chum Salmon (Oncorhynchus keta). The Humpback Salmon is also known as the Holia, which is a five-letter word, and the Chum Salmon is also known as the Keta, which is a four-letter word. Both species of salmon are found in the North Pacific Ocean and are important sources of food for many cultures.
