i have an akc account and can 'manage' dogs on the site and look through registered dogs and I typed in his name and his info came up.
you would have to make an account to be able to access his info and then once you have made one you can go over to the tab on the side and click 'manage dogs' and then click add dog, then type in his name, wait for his name to pop up on your computer screen, and then add, then you go from there and look up the info provided.
I haven't been able to find anything on juno von roxie though
If you set up an account on the AKC website (it's free, and no you don't have to be a breeder, anyone can do it) you can look up an individual dog. However, only info that will give you is dog's name and registration number. You cannot research pedigrees on the AKC website. Only way to get a pedigree from AKC is to purchase it. Can't get it for free.
And a pedigree still won't tell you anything about the dogs, just lists the ancestry: names, registration numbers, colors, any AKC titles they held. That's it. Though once you know the names of the ancestors, you can probably research more about them through other sources.
