"Your dog is hungry, George."
Translation:كَلْبَك جَوْعان يا جورْج.
Please see the following comment:
No. 1 and No. 2 are the standard grammar (ie. in the nominative case). No 1 is for a dog's male owner (George) while the second is for a dog's female owner.
For the above sentence, it is No 1.
No. 3 and No. 4 are according to some specific Arabic dialect (in any cases). No 3 is for a dog's male owner (George) while No. 4 is for a dog's female owner. So, it's No. 3.
But, as the course title is "Arabic" and not a specific dialect, the sentence should use No. 1.
Is that your question?
