My neighbors recently adopted a shepherd mix, cute little dog, still has a lot of puppy in her. This dog gets loose all the time. I've had to rescue her a few times when her people weren't home. she has a talent for finding weak spots in fencing. They started leaving her on a tie outside, but she slips her collar and is off and running. I'm concerned that she'll run afoul of cars or other dogs, so I was thinking of buying her a heavy-duty harness like the one Zena has, and just leaving it (anonymously) hanging on their fence in a gift bag. I guess I'm going on the theory that these people don't know how escape-proof a good harness is, or maybe funds are tight. I just don't want to offend or irritate them. What do you think, guys?
