It is against the law not to clean up after your dog. Small plastic sacks are available from many shops for a very low price and are ideal for cleaning up after your dog. Anyone identified allowing his/her dog to foul in a public place will be issued with a fine of up to €150.
To report incidents of dog fouling, please contact the Dog Control Section at 01-205 4771. The council can only tackle this problem if they can identify the offenders, so please report them when you see them straightaway!
