I've searched in these forums and other sources but am very confused. We will be taking our dogs to Northern Italy and Southern France in mid May for about a month. We want to do all we can to protect them against all the nasty things they could get. It seems that Milbemax should cover them for the worm type things- including lungworm (I think that may be a quite recent change - I read that Advocate was the only product to prevent lungworm but I think that's out of date????) and Advantix (which we use against ticks in UK) should protect against fleas, ticks and sandflies. But - I've read about a Spanish vet recommending Advantix and Cardotek and Scalibor collar. I'm not sure UK vets prescribe Cardotek (I think Milbemax does the same) and I don't know why the Scalibor collar would be recommended if you are already using Advantix. Other sites say that you shouldn't use Scalibor and Advantix together. Can anyone help! Many thanks.
