My dog "Bear" was having a poo behind a hedge last week and a 55kg albino Alsation T boned him after coming through the hedge with the owner being pulled by the dog on an extendable lead... i told the owner who is about the same weight as the dog to pull it off and he couldn't. He then let the dog off the lead when it came back and nipped at my dogs ribs four times. I got between the dogs and to be honest i lost the plot a bit and shouted at the owner to get it back on the lead. I got mine on the lead and made a gap between the Alsation and us but the owner was wanting to make more of it and was encouraging the dog to go for me. Last week the police were at my door saying he had made a complaint to them about me and the accusation was dismissed when i made my statement as he has made this type of claim a few times in order to get moved from the area he stayed in (racial abuse).
The thing is this dog has attacked three others dogs recently and my dog once before and he assaulted a dog owner just a month ago after the chaps dog was bitten and i am going to take it further and i want this dog put down before it kills another dog or bites a human. The Police indicated that i should get evidence of its past behavior but where do i go from here guys?
