Dog Hair On Clothes

Hi ladies, I’m staying at my fiancé’s house to dog sit while they went away for the week. Ive been washing my clothes fine but i noticed the dog has slept on a onesie i forgot to put away. It was covered in hair! I ran it through the washing machine for 15 mins but it didn’t remove the hair. Ive stuck it back in for a 60minute wash to see if that helps. Any idea how to remove the hair will this now affect any other clothes i wash in there from now on? I don’t want all my clothes to have dog hairs on?!

Ive read to do a rinse once the clothes are washes with an empty machine to help get rid of hair from the machine but will this work? Any advice please?!?
