It’s and its
These two little words often cause a lot of confusion. How do you know which one to use?
It’s is a contraction of it is or it has. It has (or it’s) been a hot day today.
Its is a possessive pronoun meaning belonging to it. The dog was known for its constant barking.
A way to test it
If you can replace it[']s in your sentence with it is or it has, then your word is it’s; otherwise, your word is its.
