dog aggression

hi guys thanks for all the reply's been having a few difficulty's with buster and his behavior with other dogs .Hes started to get aggressive and territorial And its very hard to get him to listen to me .can anyone give me some suggestions on how to curb this behavior as its getting worse by the day .he has got a lovely temperament with humans but gets all defensive when he sees another dog and he is getting stronger by the day

Spin him when you can and let other dogs sniff his bum. Will hate it at first but will get used to it and learn that he doesnt have to worry about it. Speak to him while you do it for reasurance and best try with owners you know so they know whats hapening

thanks Nathan i will try that but the problem is some people look like they are terrified of him .i have got a friend whose got a dog and will try and get them to do what you suggested as its driving me nuts and im always looking ahead and dont feel relaxed when out with him
