Dog runs home with animated Belgian (3,3,3)
I believe the answer is:
rin tin tin
'dog' is the definition.
(I know that Rin Tin Tin is a dog)
'runs home with animated belgian' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'home' becomes 'in' ('he's home' can mean 'he's in').
'with' says to put letters next to each other.
'animated belgian' becomes 'Tintin' (Belgian cartoon character).
'r'+'in'+'tintin'='RIN TIN TIN'
(Other definitions for rin tin tin that I've seen before include "Canine star of many films" , "shot dog" , "Fabled canine" , "Dog Star" .)
