"If you are caught you will be fined"....
Apparently not in East Hertfordshire...http://www.bbc.co.uk/news/uk-33064119
"The BBC asked the 348 local authorities in England and Wales which deal with dog fouling about fixed penalty notices. The figures come from the 302 authorities which responded.
Of those, 103 did not issue any fixed penalty notices in 2014-15, and 48 had not issued any in the last five years.
These included Bexley, Swindon, Bournemouth, East Hertfordshire and Merton councils, which between them received almost 8,000 public complaints about fouling from 2010-15."
