"You know my dog."

Translation: Vous connaissez mon chien.

[mjbat7]

I used sais instead of connais and was marked wrong, was wondering why?

[GraceEstes3]

Savoir=to know (as a fact)
Connaître=to be familiar with (such as a person or topic, you've been introduced with it before)

[max.vinten]

Why is vous incorrect? Is there anything about this sentence that calls for the informal "Tu" apart from the friendly nature of the phrase?

[deactivated user]

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.

I wrote: Tu connais ma chien, why is it wrong?

[nobbelfludd]

mon chien or ma chienne

[francisco1121918]

Because chien is male, you should have said tu connais mon chien, or if yoh have a female dog, you should have said tu connais ma chienne

[KunHuo]

I used tu and it was marked wrong, I used connaissez, was I supposed to use connais?

[Rana4746]

The verb connaitre conjugate to: tu--->connais, vous--->connaissez
so you should have said tu connais mon chien or vous connaissez mon chien.
