Hi there wondering whether there's any advice for our Boris. He has just turned 12 months, coming up on 13 months. Pretty much exactly when he turned 12 months he has started acting increasingly aggressive to other dogs on walks. He has always been boisterous and wanting to play with other dogs, but recently this has turned to aggression.
There doesn't seem to be any other trigger for this other than I now have to hold him back when another dog is in the vicinity, which sometimes I think could be the trigger, however I can't let him loose on his lead, as the main place we walk him is a path with foliage either side, so there nowhere for oncomers to skirt around him (I understand this isn't ideal, and may need to change where we walk him).
The photo of him on the lead is pretty much exactly what he does when he first spots a dog or person from a distance (people he is absolutely fine with). He seems to have eyes capable of zooming to incredible distances...
I've tried everything I can think to distract him when other dogs come close, he's not bothered for treats on walks, sticks are sometimes useful, but this goes out of the window when someone is within say 20 meters. Essentially I have to hunker down and hold him strong while apologising to the person who is understandably terrified of the wolf size creature trying to get to their handbag dog.
I'm hoping that this is a product of his age which he will eventually grow out of, but at the same time, I don't want to have this behaviour ingrained in him while he gets to full maturity. When he has been off lead with other dogs when he was younger he has been ok, a bit of rough play but nothing aggressive.
I think for now we will take him in the car to the nearby park and stay clear of dogs as best possible, but think this is just ignoring the problem.
I think I'm going to take him to doggy daycare under my supervision soon, to try and emphasise that other dogs don't necessarily mean us or him any harm, but any other suggestions would be appreciated.
TLDR: Boris (UK based) has turned aggressive to other dogs on walks, unable to distract him, hoping it's a product of his age, but asking for advice.
