Well that's a shame. I also bought the flea treats and have been giving them religiously. I didn't trust it enough to stop the AdvantixII, so we're good here
Oh well, they're good for the dogs anyway, helps boost their immune system. I have to hide it in their soft food, though, because Izzy won't eat it and I have to give them everything the same, siblings
Anyway, that's a great idea to split the dose of the flea meds. I am very lucky that neither of mine have ever had any reaction.
