They cure noise made by cattle dogs (7)

'by cattle dogs' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see a link between them that I can't see?

'they cure noise' is the wordplay.
I cannot quite see how this works, but
'cure' could be 'heal' (synonyms) and 'heal' is located in the answer.
The remaining letters 'ers' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'made' is the link.

Can you help me to learn more?
