could be kev but why not use a pic of his or did he spot mine on the net and liked it then said it was stollen from him in the hope he would get my dog ????
Here's another theory.... Perhaps he's being telling folk that your dog is actually his for however long on Facebook etc, and now with the season starting up, perhaps someone who he's told the dog is his has organised a day/night out to see the dog run, the lad perhaps sees what he's done as the only option to get out of it?
could be ross f**k knows pal he was a funny young lad bit strange
