Male and Female?

I have a one year old chin male named Milo. He is a black velvet and has one his way into my heart after only a month. I bought him alone, the old owners didn't take very good care of him. They placed him in a small cage all by himself and I'm currently trying to find him a friend before he gets depressed. If I got a neutered female do you think it would be possible to bond them? I'm to young and inexperienced with chins to breed yet but whenever I'm looking I can only find females. I haven't got him a friend yet I was just wondering if it could be possible. Also is there any way of seeing if a male has been neuteured? The previous owner said she didn't know if he was.

Thank you!!
