Terrible slur worried dogs (4,8)

I believe the answer is:

bull terriers

'dogs' is the definition.
(bull terrier is a kind of dog)

'terrible slur worried' is the wordplay.
'worried' indicates an anagram.
'terrible'+'slur'='terribleslur'
'terribleslur' anagrammed gives 'BULL-TERRIERS'.

I've seen this clue in The Telegraph.
