oh Linda am just now reading this . . how is the little stud muffin doing? both my babies haven't had any frontline in a long time . . I think I only tried it on them ones but did not have a reaction. . .both of mine are 95% indoor so I never felt the need to get it on them . . .I do hope that Jake will get better soon . . . .you and your family are in my thought and prayers.
