Milbemax only treats some strains of lungworm ,my dogs get milbemax every 3 months from pup plus drontal ,and flea treatment .but my whippet x got lung worm and 3 different vet practices said kennel cough and ruled out lungworm .
i sent a sample to worm count and it came back fox lung worm .he was on treatment for ten weeks and at times I felt I was loosing him it got that bad .i really don't trust the vets round my way ,6 times they said kc and alls it took was a poop sample ,I didn't no about worm count as i would have done it weeks befor I did ,he had to have ct scan and camera couple
