Hey Ed! I'm so glad you started this site. I can't wait to see what it develops into! I've often wondered about dog actors, whether two similar dog characters were played by the same dog, etc.
Anyway, my suggestion is twofold; firstly, to add Sebastian, the dog/puppy from The Sixth Sense (film). Upon viewing the film my first instinct (based on the facial markings and overall body shape and size) was that he was an Alaskan Klee Kai. However, the only information I could find on him (which wasn't much at all, and definitely wasn't from a reputable source) stated that he was an Alaskan Husky. Could you shed some light on this? The puppy is super-cute and I'd love to see what else, if anything, he or she has acted in.
The second suggestion is more general site-related; browsing the site, I have a few comments about the interface and presented info. I think it might be helpful to include links to the IMDB or Rotten Tomatoes page for the film or show discussed in an article. I also feel that the 'retriever' and 'golden retriever' categories should probably be merged
Also, it would make more sense, I think, in films or shows with multiple dogs (most noticeably Up), each dog should have their own page to ease confusion.
Thanks for your time, and good luck with this awesome site!
