You can download any of these breeds easily just by going onto: Downloads, Local Disc, Program Files, Ubi Soft, Studio Mythos, Petz 5 and if it's a breed, you put it into Resource, Dogz/Catz (it depends on which it is) however if it's a pet from the shelter you put it in Petz 5, Adopted petz. Iv'e explained that as fully as I can and I hope that it works just as well for you as it did for me!
Please feel free to download as many things you like from this website and I will try and update it as often as possible!
