They should meet on a neutral ground. If he's been king of the roost for so long he might get possessive of his stuff. It's always best to introduce dogs on a neutral ground,I've never seen an undocked poodle with a curly tail but it's plausible that she can be a mix. I think if you left her tail long and fluffy like a Shih Tzu it will be fine and really cute.
I used to rescue/foster poodles and have a big soft spot for them
I hope it works out. Just be patient and have a nice slow introduction before you bring her into the house. Maybe a park or something so they can get used to each others company.
