There were lots of abandoned buildings around everywhere, including Alofi. In Tuapa, there is a big field where a pack of dogs raced over barking and biting at the bicycle. I just kept going and shouted at them, but was quite frightening. Later I learned this always happens in Tuapa, as Alexa, Brian, and Ira immediately knew what I was talking about. The recommendation is to yell back at them and stand your ground. Some other tourists I met claimed the dogs even attached their car and bit the tires as they were driving by!
