I would train her on leash around all kinds of dogs, including small, if I were you. It honestly doesn’t sound like your dog was horrible. Yes, blowing a recall wasn’t any good, and I’m assuming that both dogs were technically supposed to be leashed, but she also wasn’t acting aggressive if she just wanted to play.
IMO, I would have her on a long line from now on, until she’s proven herself capable of working around all dogs — no matter what size. I don’t personally think it’s really a huge deal that you haven’t worked her specifically around small dogs up until this point. Now you know it’s something you need to work on, and you can start.
