We got Maxi's recall (lot like yours with greeting other dogs) sorted using a pager. Worth considering if you haven't already. The pager interrupts their thought process - must bomb over to other dog, jump up etc. - then they accept recall - then treat. Didn't take long and now I don't user the pager, really only a safety precaution.
No - literally like a pager. Either vibrates or makes a ping sound. Just reminds your dog that they are supposed to be listening to you rather than haring off or whatever. Dog walker recommended to us.
