Stringbag & I were attacked by a pair of rehomed American Bulldogs a couple of years ago. I had to lift him up to stop him being torn apart, and as a consequence had to suffer bites on me,
The Police were involved, but about as much use as a chocolate teapot, and it never made court but the dogs were big, powerful and off the lead.
I've had dogs all my life but I'm now scared if any big dog comes near, even if it's on the lead..
