Yours truly surrounded by Bolshevik’s dogs (3,7)

I believe the answer is:

red setters

'dogs' is the definition.
(red setter is a kind of dog)

'yours truly surrounded by bolshevik's' is the wordplay.
'yours truly' becomes 'setter' (the person that set this crossword).
'surrounded by' is an insertion indicator.
'bolshevik's' becomes 'red's' (type of communist or 'red').
'setter' put into 'reds' is 'RED SETTERS'.

I've seen this clue in The Times.
