Memorial for a type of terrier (5)
I believe the answer is:
cairn
I believe this is a double definition.
'memorial' is the first definition.
(type of memorial made from piled up stones)
'for a type of terrier' is the second definition.
(I've seen this in another clue)
(Other definitions for cairn that I've seen before include "simple grave marker" , "Memorial mound of stones" , "Stones piled up as a marker" , "Piled-stone marker" , "Burial mound" .)
