Now, I recently caught a Smeargle and wanted to breed it with my Ditto, but I haven't gotten any eggs yet. My Ditto has already advanced 12 levels just from sitting there.
you have to see what the mans says about how they get along, if he says the prefer to play with others they wont breed. you might have to switch either ditto or smeagle.
If it says anything else, they will breed but it may take a little while.
