Today I was walking my dog around the complex grounds (leashed of course) and my neighbor's poor dog comes bounding around the corner, unleashed. She is no where to be found (neighbor). This is a dog who NEVER goes out for more than 5 minutes (I see her let him out and bring him in). He's a lovely collie type dog who is home 8-10 hours alone (the dog 'mom' is a single woman who works).
Fortunately we know this dog by sight and he is about the same size as my dog so she was pretty calm. I told him to go home (the neighbor's dog) and he was very skittish.
If I didn't have my dog I would have taken him back to her and remind her that 1) that unleashed dogs are not allowed on these grounds
2) he could get hit by a car
I would have taken him in...he is such a lovely dog...
The worst thing you can do is keep a dog locked up and NEVER walk him. My parents had dogs like this (we had a big yard w/a fence, though). They are so likely to bolt...which this dog obviously did.
