Can I borrow them please, there is a fox coming in my garden at night and the place stinks!! my dogs GSD's mostly choose not to hear it,(it disturbs their sleep lol) having said that, if they saw a fox then it probably wouldn't last long, I live on a farm over-run by the bl***dy things, I recently had to fork out over �100 to treat all my dogs for mange as many of the foxes around here have it, don't worry about what others are saying, I doubt they would be so concerned if you had said it was rats your dogs had killed, foxes are classed as vermin as well. and just because a dog does what nature intended doesn't make it a baby killer.
