Few games focus exclusively on online dog breeding. Most integrate it as a subsystem.
| Game | Platform | Breeding Depth | Online |
|---|---|---|---|
| Nintendogs + Cats | 3DS | Breed compatible pairs → puppies inherit traits/colors | Local/StreetPass only |
| Dogz (Ubisoft) | DS, PC, GBA | Breed, raise, show; genetic traits | No |
Zoo Tycoon 2 (PC) + "Endangered Species" + "Marine Mania" – Detailed genetics, conservation breeding programs. Community mods add dog breeds. Single-player only.
