The term "dog-style" typically refers to a sexual position where one partner penetrates the other from behind on all fours, much like dogs mating. However, there are a variety of synonyms and euphemisms for this position, depending on the context or preference. Some alternatives to "dog-style" include "doggie-style," "canine position," "rear-entry," "reverse cowgirl," and "bottoms up." Additionally, some less explicit phrases can be used, such as "backdoor entry" or "from behind." Ultimately, the specific synonym used may depend on the conversation and the speaker's comfort level with discussing sexual topics.
