SIR – My husband and I often walk along Prestwich Avenue and follow the footpath running beside the playing fields off Nunnery Wood Primary School on to the lake at County Hall.

We did this walk only to find at least four heaps of dog excrement in a matter of just a hundred yards. Not only are the dog owners showing no consideration for other walkers, but they are breaking the law and liable to be fined.

NANCY DYSON,

Worcester.
