In recent months, the presence of dog poo bags being left in woodland areas is becoming more common. As you can see from this image which was taken in August in a woodland area in Saggart the poo bag is swinging from a tree. Dog owners may think bagging up after their pet is the best thing to do, but the ‘poo bag’ needs to be disposed of correctly in a bin not left in the woodland. The plastic bag will take anywhere from 10 years – 1000 years to decompose.
