How very very horrible for you fuzzyboots. My girlfriends dog was attacked by the same dog a couple of years ago in the same place. Fortunately she survived and it cost her a lot of money at the vets. She has never let her dog off the lead since, as a direct consequence of this attack. Regarding the Staffordshire dog owner, Peckham Rye attracts Scum more frequently than Dulwich Park so I would avoid wherever possible.
