From my experience, prevention is far better then cure, even though we followed a worming regime to lessen the risk onew of my springers still contracted lungworm, apparently Panacur kills one stage and Advocate or Stronghold another stage, but if if the parasite has progressed past those two stages then a large dose of Milbemax administered under vet supervision because of the risk of shock is effective against the later stages of the parasite.
My 5 year old springer was fortunately diagnosed with it fairly early on, even so the lungworm has left him with congestive heart failure and restricted lung capacity, the first symptom he showed was a slight weight loss then a dry cough, this was diagnosed as kennel cough until he coughed up blood and X-rays showed an enlarged heart and bloods revealed parasite spores.
He is now on medication to support his heart, is happy and still running around like a loon although he does get tired quickly, and we're told he won't make old bones.
my springer is a the second in a year I've heard of with lungworm, the first was a springer I re-homed to an adoptive family, he died suddenly after weight loss and a post-mortem showed lungworm infestation.
We are in West Cornwall and I'm told by my vet that Lung worm is a problem here and also in Wales and the South East, cases have also been reported in Scotland.
