What were you hoping the police would do?
this is a dog on dog attack?
The police do not secure compensation.
A dog on dog attack is not covered by the Dangerous Dogs Act or the criminal law at all. The only interest of the police is a dog that attacks a person and even then they do not secure compensation.
You could sue in the civil courts although the Animals Act 1971 does not automatically render a person liable because there was a dog attack.
Also, there is no power to direct that the dog be kept on a lead as indeed dogs cannot usually be kept on a lead permanently.
Can I clarify anything for you?
Hitting your sister is a common assault and that is covered by the criminal law.
Senility is not a defence although it may impact upon the sentence he receives and the public interest of prosecuting.
All the best.
