'children's stories' is the definition.
(stories for children)

'reasonable having young dogs speaking' is the wordplay.
'reasonable' becomes 'fair' (synonyms).
'having' is a charade indicator (letters next to each other).
'young' becomes 'y'.
'dogs speaking' becomes 'tales' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'fair'+'y'+'tales'='FAIRY-TALES'

'in' is the link.
