What is the best site or publication for identifying caravan parks that will accept our dog?

WikiCamps by far. Runs on Win8 or above, Android and Apple.

http://www.wikicamps.com.au/

For a website http://myparklist.com/ listed virtually all caravans parks, showing those which allow pets.

Will the wiki thing work on my laptop computer?

Yes as long as it is running Win8 or better, android or mac.

If you use or have a GPS Navigator then you can download dog friendly van parks, camp sites etc as POI (points of interest) and load them into your device then search on it for Pet freindly..... and it will list them and give you instructions how to get there...
