"You know my dog."
Translation:Vous connaissez mon chien.
In french, like in spanish, sais and connais aren't interchangeable, but we have no specific equivalents in english. connaitre is used for knowing people or things, being familiar with them. Savoir is used for knowing facts, more like knowing on paper, if that makes sense? For example, you connais your mother, but you sait that she likes the color blue
Thank you! I always struggle with savoir and connaître so this really helps!
What was the verb that you used for "know" and how was it conjugated? I'm guessing it was that rather than the tu/vous usage? Duo wants you to use "connaître" here so you would have to say "vous connaissez" to have a correct answer.
