Way too excited around other dogs! What to do?

We've had our rescued 2 year old Peke, Ebi, for about two months now. She's doing really well, but one problem we don't know how to fix is that she *FREAKS OUT* when she sees another dog, either in person or through the window. She jumps around, frantically barks, and doesn't even realize we are there, until the other dog is out of sight. I don't think it's aggression, just excitement.

We've had her around two other small dogs. One she played really well with, they rolled around the house but it never got too aggressive. The other one is shy, and Ebi mostly ignores her because she won't play back.

I don't want to close the window, she LOVES to look out of it, but her frantic barking is intolerable. I don't know what to do, because she doesn't even realize I'm there if a dog is present. I'd love to set up a regular doggie play date, but her behavior is so bad that I don't want to inflict her upon other dogs and their owners. Any suggestions would be very appreciated!
