Attack report:

I was walking my Doberman around my neighbourhood when someone else was coming the other way while my dog showed no aggression the other dog attacked his nose for no reason, after trying to get him away he latched on to his hind leg for about 10 seconds the owner just watched with all my efforts to get him off. The owner then let him off the leash and he/she attacked my dog again. I was able to get him off quickly and got him to safety so i didn't get the chance to get the owners details.
my dog is currently undergoing vet treatments and will need to go for further consultations. The incident happened at approx. 5.30pm 22/05/2020 outside the Playford Tavern car park northern side so there must be camera footage of the incident.
