Apparently I filmed this on the 4th of April, 2010(my phone back then was a Sony Ericsson k660i).The building material cover that the Wurm is on is right next to our dog's enclosure. Our dog has had the proper medicine, so I suspect the parasite came from a fox as they visited really often around 2008-2012 or so. I've actually seen a fox sit meters from the enclosure pissing my dog off, whilst taking a shit. I couldn't break the parasite by just pressing with a shovel as it was quite though...had to proper hack it to pieces(obviously it wiggled around for some time after that).
