Phone the Council Environment Section. Also worth trying would be your local HSE office. Councils would take this very seriously. As for previous thread comment (off topic) that pertained to barking - a dog warden has NO REMIT whatsoever in this. check the law on this if need be. My local warden is very good, operates a policy of as little or no kill policy as possible and fulfils his remit. Barking is not his remit and is commonly but wrongly thought to be the case.
