A Sydney surgeon has been handed a two-year good behaviour bond after he broke more than a dozen ribs of his former girlfriend's papillon dog.

Oncologist and Macquarie University lecturer Nicolas Oddone was also fined $5000 and ordered to pay more than $15,000 in vet bills and legal costs on Thursday.

Oddone, 40, was found guilty of one count of animal cruelty last month after he severely beat Prinny, owned by the woman he was dating, at a Woolwich unit in June 2013.

The bashing also caused the dog to suffer a collapsed lung, internal bleeding and muscle damage, according to documents tendered by the RSPCA.
