Firstly, could I please ask what a chocolate yorkie is? I've never heard of one over here.
I'm so sorry you lost Toby & can quite understand how you're feeling having lost so many through the years.
As you're not planning on breeding, I think the main thing is to find one that you fall in love with & meets what you're hoping for enough that you know you won't regret the decission.
He won't replace Toby in your heart, but make his own little space in it.
Good luck in your search.
