I dont th ink that horses,goats etc really come into it.If you didnt clean up after your dog in the UK,then thats one issue,and if you now dont do it here,because you aren't liable at the mo to pick up a fine,thats another.Get yourself a look at " Me,myself and Irene" to see a possible solution to those who think its acceptable,bio-degradable!!What a load of crap!
