We use possessive adjectives (my book, our home, their family) to show that something belongs to somebody. You have to remember their forms.
||I like my job.
||You like your job.
||He likes his job.
||She likes her job.
||The police dog likes its job.
||We like our job.
||They like their job.
We always use possessive adjectives together with a noun. We don't need an article when we have a possessive adjective:
I have a family. It's my family.
You have a dog. It's your dog.
He has a new phone. It's his new phone.
She has a black dress. It's her black dress.
We have a child. It's our only child.
They have an old car. It's their old car.
Its ≠ It's
Do not confuse its with it's (= it is).
