I have two dogs who I love dearly and one of the issues that really strikes fear in me is the possibility they could get lung worm as it can be fatal. For this reason I buy them a flea and tick preparation from the vet which also prevents lung worm. I'm in the UK so I don't know if it is sold in other countries but it is called Advocate. For all you dog lovers out there do you know about lung worm and do you protect your dogs against it?
