"The dog hurts me every night."

Translation: Gortaíonn an madra mé gach oíche.

[khmanuel]

Can't you put the me at the end?

[scilling]

Either before or after gach oíche would be possible.

[galaxyrocker]

Yes. I also feel it would be more natural that way as well, though I am unsure in this case because the time adverb.

[Searlasmane]

gach uile oíche?

[GrahamMontrose]

Yes, this is why only cats are aloud on the bed.
