Crossword Genius

Terrible slur spread about pedigree dogs (4,8)

Ross

I believe the answer is:

bull terriers

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

'terrible slur spread' is the wordplay.
'spread' is an anagram indicator.
'terrible'+'slur'='terribleslur'
'terribleslur' with letters rearranged gives 'BULL-TERRIERS'.

'about' acts as a link.
