Crossword Genius

Caring guy, her Don, arranged sport involving dogs (9,6)

I believe the answer is:

greyhound racing

I'm a little stuck... Click here to teach me more about this clue!

'sport involving dogs' is the definition.
I can't judge whether this defines the answer.

'caring guy her don arranged' is the wordplay.
'arranged' indicates an anagram (letters rearranged).
'caring'+'guy'+'her'+'don'='caringguyherdon'
'caringguyherdon' anagrammed gives 'GREYHOUND RACING'.

Can you help me to learn more?

(Another definition for greyhound racing that I've seen is " sporting events".)
