I can't speak from personal experience of cruising with a dog, but as a dog owner I just don't think it would be fair to the dog in most circumstances.
I'm erring on the side of agreement, except in a case where the breed (I'm totally un-educated on this area) was suited to lots of swimming. I'm told something Spanglish might be great for this.
On the other hand, Cats I get. Long shipping tradition, Mathew Flinders, Trim, etc. And no matter what animal it was, I'd be getting it from a registered Australian organisation such as the RSPCA.
Back to the point... South East asia... Thoughts, opinion, comment?
To coin a phrase I heard in a pub one time "Grow a pair", and have your say.
