My girls are rarely on the lead. When I see another dog approaching on the lead, I do call them to me and keep them close as we pass by.
Marley and Stevie are very good at reading other dogs' body language though and do avoid certain dogs.
Although I am wary of 'staffies' (sorry, I know that is breedist), I do give them the benefit of the doubt and try to act the same as I do with other breeds.
The dogs that give us the most grief are usually small terriers (usually on the lead) who can spot my dogs from a distance and start yapping and straining to get to them.
There are four terriers who live at a property on a regular walk. They never go for walks, I think their exercise is racing from vantage point to vantage point in their garden
When they spot my girls they start going ballistic
.
One day, the smallist terrier got out through a gap at the bottom of the fence and flew at my girls
What was really comical though was when it realized it wasn't behind the fence and it wasn't being backed up by its 'pack'.
It didn't know what to do and just froze then casually went back under the fence, tail between its legs
