Linda,
I am petrified of Frontline. I only give it to my boys now when I will be home with them all weekend. I am willing to put money on it that Dexter has a mild reaction (which is enough to scare me) when I give him 1/2 a dose of it. I split one tube between both my boys and my Dexter becomes lethargic and very very needy and vomits multiple times when I give him frontline.
Oooh poor Jakey!

I am soooo sad! I pray he heals quickly and fully. (((HUGS)))
