I was once out walking my staffy and bull terrier when an offlead black lab charged us; hackles up, slavering, growling - without a shadow of a doubt on the attack. With two dogs I couldn't pick them both up so picked up the smaller, and then shouted aggressively at the lab, whilst its owner (giving up on any recall - cos it had none) puffed and panted upto us, with the usual "He's only being friendly!" Yes. With his hackles up and snarling. Very friendly. Luckily I was wearing big walking boots and as it got nearer was prepared to kick it in the face if it had touched my dogs.
Being bull terriers, if it had started a fight they would have finished it. And as it was a remote field with no witnesses, probably got the blame if they'd killed it. I told the woman she had no business letting that thing offlead if it had no recall. She was very entitled, "who are you to tell me what to do?"
But I never saw that dog again. She had a fright and walked it elsewhere.
All the time it was happening, my two bull terriers looked - one of them scared, one of them totally non plussed. I had no doubt that even though they were on lead and under control and the 'loveable' labrador offlead, with no recall and a slavering, vicious mental wreck - my dogs would have got the blame had a fight ensued.
I found it very hard to believe that this woman (a) fantasised she had any recall and (b) genuinely believed that a dog charging two other dogs from a great distance, with hackles up and teeth bared was "only being friendly".
The neighbours I have now have the same sort of dog and that is also incredibly aggressive and reactive - to the point we can barely use the garden as if it sees us out there, it goes for us through the fence.
Ever since I always walked the dog(s) wearing bovver boots and with every intention of using them if I had to break up a fight and prevent injury to my own dogs.
