I am a dog lover, and when I have a dog, I am as soppy over it as any other dog lover.
However, if I knew my dog was nervous/territorial/liable to bite, then for the dog's sake, I wouldn't have it there at a large gathering, which it could find stressful - leading to it being more likely to bite. All those extra people, extra noise, it's safe home being over-run by what sounds like a lot of strangers (strangers to the dog, that is). It would be highly stressful for the dog.
For that reason, I would either not host, or would find alternative care for the dog for the day.
I think there's something underlying the cousin's refusal to compromise so that the 3 year old can attend - although the point still stands that if the dog is territorial and liable to bite, then all guests are at risk.
But as has already been pointed out further up the thread - it's not like the New Zealand family won't have a further opportunity to meet the three year old - presumably it's an all-inclusive family and the child will be at the wedding.
I'd not make a huge song and dance about it. And I'd certainly not be trying to stir up trouble amongst the other guests by saying why the child wasn't at the party.
