I believe the answer is:

husky

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

'dog' is the definition.
(husky is a kind of dog)

I don't understand the rest of the clue.

(Other definitions for husky that I've seen before include "hampered by frog?" , "Arctic sledge dog" , "sounding a little hoarse" , "Arctic sled dog" , "Big, strong; dog" .)

I've seen this clue in The Sun.
