recently my dog got out of the yard and ran to the neighbors and ran all around their house upsetting their dogs! it was quite annoying but eventually he came to me after i called to him for a bit.
yes it was quite distressing as i live next to a major street! luckily he did not cross it and simply went next door but still!
oh man, i hate it when my dog starts barking at the neighbor dogs too. i would be so mad at him for getting out though.
