TWO "danger dogs'', found dead and floating in sewage at a treatment works, may have been dumped down a manhole on purpose.

The bodies of a bull terrier-type bitch and male were found on Monday by a member of staff at the waste water treatment works on Mill Lane, Great Harwood.

It is believed they had been trapped in a pipe at the works.

Horrified RSPCA inspector Katherine Hamblin said she fears someone may have panicked following the recent outcry over dangerous dogs.

The treatment works takes in water from various areas but it is believed that the two animals were sent to their deaths in Accrington or Oswaldtwistle.

Inspector Hamblin said: "We can't be sure yet but someone may have dumped the dogs down a manhole and they were then swept along.

"They had been in the water for some time and, although they haven't been properly identified yet, we believe they are bull-terrier types and both quite young.

"If someone has dumped these dogs then it is appalling that someone could dispose of an animal in this way."

The two dogs are cream or tan in colour but the male has a white chest, a black patch on his right eye and a docked tail. The bitch has no distinguishing features and neither dog was wearing a collar.

Last month, Councillor Brian Roberts called for a dog amnesty in Hyndburn after the fatal attack on Ellie Lawrenson who was killed by a pit bull-type dog in St Helens.

During 2006, 13 dangerous dogs were seized in the borough, some of which had been specifically bred to be fighters.

Inspector Hamblin added: "We don't want people to over-react about dangerous dogs. There are plenty of options available to help them.

"We would always advise dog owners to contact their local vet if they are at all concerned about their pet."
