Realize that it could be something entirely different such as some vegetation in the yard . Nearly all frog secrete a substance that causes irritaion and different species are more dangerous than others, I have read of some dogs almost obtaining a sort of "high" fron this . They will lick or mouth them for the feeling they get from it ( or from what I have read.) It could quite possibly be the frogs .I woul investigate the yard for any plants that may be toxic to animals.
Hope you find a solution
