Terrier was shown something brown to drink (8)

I believe the answer is:
airedale
'terrier' is the definition.
(Airedale terrier is an example)
'shown something brown to drink' is the wordplay.
I cannot quite see how this works, but
'shown' could be 'aired' (I've seen this in another clue) and 'aired' is located in the answer.
'drink' could be 'ale' (type of beer) and 'ale' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'was' acts as a link.
Can you help me to learn more?
(Other definitions for airedale that I've seen before include "Terrier - Yorkshire area" , "Large breed of terrier" , "Thematic type [DOG]" , "Canine breed" , "Yorkshire valley" .)
