Hello again all, this is from my local council website, so it looks as if our only option if we had to would be to involve the police, which we don't want to.
''Dangerous Dogs
Dangerous dogs are the responsibility of the Police
If you want to report a dangerous dog contact the Police on the non-emergency number 101.
You may be required to provide the following details of the incident:
where and when the dog was last seen
what the behaviour of the dog was
a description of the dog (that is the breed, size, colour, distinguishing features)
any known information regarding the owner
You may also be required to provide evidence in Court should the owner be prosecuted.
What is a dangerous dog?
A dangerous dog could be:
a dog attacking a person
a dog attacking another dog
a dog attacking another animal
a specific breed of dog that is deemed to be dangerous or banned''
