Dog poison has been found in 4 different areas around Bielefeld. Elpkebachtal/Sieker......Stralsunder strasse.....Radrennbahn....Strahlsunderstrasse.... It could be anywhere else too. Be careful when walking your dog; or if you can, get a muzzle so your dog can't eat/pick up anything while walking outside. If you find anything strange report it to the police and pick it up and keep safe in a bag. One of the pieces found was meat with tablets inside.
