I would check with your vet on this - you don't want to overdo it or under protect them - The vet can tell you if this is feasible.
I know Heartguard cannot be shared - the medicine in the Chewable is injected into it (or however they do it) and you never know WHERE it is - so they cannot be shared - but I don't know about the Frontline. I personally wouldn't mess with it - but your vet can tell you better. |
