Milbemax, when given as you would to worm your dog, would not prevent Lungworm... Honey reacted badly to Advocate when we tried that and, as I had read that Milbemax could be used for Lungworm prevention, I specifically asked at the vets, and they checked the manufacturer's guidance... I think it has to be given every week

to be effective (it is definately far more often than you would give on a normal worming schedule).
From what the vets said, only Advocate spot-on is effective at preventing an infestation.... panacur can be given (again in very regular doses) to treat an infestation.
Obviously, the vet might be completely wrong here, but I just thought I should share what we have been told!
