I've not read all of the posts. But I run as a hobby, for fitness and mostly to keep my brain from noodling.
I've been bitten twice by dogs, I've had several close calls. Only one of those close calls was with an XL Bully "type" of dog (I'm not an expert). Many of them and both actual bites were with small dogs. Sure they're not going to do as much harm as a thing just built on muscle but they can do enough especially to a young child.
It's not only XL Bullies that can be dangerous and while 99% of dog owners are fine (it's always the owner's fault, not the dog), there is 1% who are not.
The warning signs I see are:
- Does not recall. I.e. if the owner calls the dog back, they do not respond.
- Running after other people (especially combined with the above) in a way which is obviously not in control.
- Jumping up at someone else who is not their owner. Again, especially combined with lack of recall.
- Owner does little to stop the behaviour.
- Owner blames the other person, not their dog. (One thing I've heard from two owners was "it chased you because you were running". No. It chased me because it was poorly trained.)
You know what both owners told me before their dog bit me "they're just being friendly". You know what both told me after they did "they've never done that before".
So my request, if you think you might be in that 1% or perhaps not totally sure you're not is to think it's not just about XL Bullies but about training and how much you'd beat yourself up if your dog harmed a child.
