Dog located outside animal hospital (8)
I believe the answer is:
foxhound
'dog' is the definition.
(foxhound is a kind of dog)
'located outside animal hospital' is the wordplay.
'located' becomes 'found' (I've seen this in another clue).
'outside' indicates putting letters inside (some letters go outside others).
'animal' becomes 'ox' (castrated bull).
'hospital' becomes 'H' (abbreviation for hospital on maps).
'ox'+'h'='oxh'
'found' placed around 'oxh' is 'FOXHOUND'.
(Other definitions for foxhound that I've seen before include "Hunting dog" , "hunter" , "5 [MANS BEST FRIEND]" .)
