Wanting to add

Hi I'm wanting to add a pup to my home to give my older pup a friend.
looking for small to medium size but can be bigger honestly.
It's ok if not fully trained just hopefully potty trained and neutered.
Home details- I work short shifts and do school at home.
We do a lot of walks.
My current pup is definitely a barker.
He's bout 4 years old and has been around dogs cats and kids.
I'd say my home is calm.
I'm willing to pay a small rehoming fee Thank you for reading
