So I put frontline on my babies last night... I have no idea if this has to do with the frontline or not, but my Fletcher was breathing very heavy for most of the evening after I put it on. Almost like panting, but no tounge hanging out. And then about 430 this morning, he woke up and threw up twice. Anyone have a baby who has reactions similar to this with frontline? Anyone ever hear of this? I just don't know if he is not reacting well to the front line, or if his tummy was just upset for another reason. I felt so bad for him!
