I think the only way you can see anything about ownership is if you add the dog as a dog of interest to your MyAKC account. Otherwise, the only information the Dog Lookup or Points Progression gives you is the name of the dog and registration number. Good luck!
If the dog has been shown, you can go to infodog and proceed as if you were going to enter a show. If the dog is in their database, it will fill in an entry application that will include the names of the owners. That does not guarantee that the information matches what the AKC has.
