The guides above apply across the board. The breed hubs narrow them down — the same ground covered with your breed's own numbers: which joints tend to go first, what their realistic lifespan looks like, when joint support is worth starting, where the bloat risk honestly sits, and the conditions they're genuinely prone to rather than the ones the internet repeats.

Each hub also carries the breed's story, because knowing what a dog was built to do explains a great deal about the body it ended up with.

  • Great Dane — not Danish at all. A German boar hound that traded the hunt for the sofa, and never stopped taking up the whole thing.
  • Saint Bernard — the Alpine rescuer of the Great St. Bernard Pass. The brandy barrel was a painter's invention; the lives saved were not.
  • Great Pyrenees — guarded mountain flocks alone, through the night, with no handler. Louis XIV made it the Royal Dog of France in 1675.
  • Cane Corso — descended from Rome's war dogs, and nearly extinct by the 1960s. A handful of Italians brought the breed back.
  • Rottweiler — the butcher's dog of Rottweil, trusted to carry the day's takings home in a pouch around its neck. Nobody argued.
  • Mastiff — not one breed but a family: English, Tibetan, Neapolitan, Bullmastiff and more. Between them, the heaviest dogs on earth.

More breeds are joining the library soon, including the Newfoundland, Leonberger, and Bernese Mountain Dog.
