They are written in different languages. MyDogSpace is a php package with slight modifications. MyDogSite was written from scratch in ColdFusion, as a learning tool for the language. It is still fairly basic language-wise, but functionally I think it’s a great dog search system.
In MyDogSite you can search for a dog holiday by state, region, suburb and feature, then display a detailed information page, which includes a photo and Google Map of the location.
I’m still planning more improvements to MyDogSite – more automation, a club search, and more content, but it’s a good start.
