A couple of mornings ago a massive Great Dane chased my cat onto our property. Our front boundary is quite low and there is no gate so it was able to make its way to the back of the house. I'm not annoyed at the fact it chased my cat, just amazed that the owner had decided to have no leash for such a big animal and he no control over the dog whatsoever. I have a newborn and it frightens me to think of what could have happened if I was out there at the time. The owner was very apologetic and clearly embarrassed but I just wondered, aibu to be angry at the dog owner or is it my fault for not having a higher fence and gate on the front?
