  1. dog: "I don't fear you! I'll call my cousin, the bone-crusher!" cat: "yeah, do it. I just want to have a chat with him."

  2. How dogs avoided being exterminated by cats? They run.

  3.  @MrClassicmetal  The tendency of pumapards to be smaller (about half the size) of both parents and comparatively short-legged is quite interesting. I'ts like mixing the genome of so distant relatives, instead of creating an "average" of the two, the offspring looses the evolutive specialization of the parents (that made them big and long-legged in respect to early feliforms), reverting to a more "primitive" shape.

  4.  @Reyma777  Yeah. That (long body, long tail and short legs) seems to be the "basic mammal predator form". All the modern mammal predator families derives from animals of similar shape. I wouldn't be surprised if, when felis and panthers diverged, their last common ancestor had more or less the dimensions and shape of a pumapard.

  5. The pitbull has not even the strongest bite among dogs. Bone-crushing animals, like spotted hyenas, are in a different league.

  6. Actually genetic analisys shows not only all of dogs derive form the wolf, but all of them derives from a specific variety of wolf, the holartic grey wolf, from which they separated only 40.000 years ago, while the Himalayan, Indian and Italian wolves belong to different haplogroups.

  7. Actually the spread of dogs in the old world led to the extinction of almost all the dog-like hyenas, that occupied their same evolutive niches, while the bone-crushing hyenas, that occupied there the same evolutive niche of the bone-crushing dogs in America, survived. So there's still something very similar around.

  8.  @danielowens2913  Spotted hyenas are active hunters AND scavengers. Actually hyenas are the "dogs" of the old world. Similar due to convergent evolution (they occupied the same evolutionary nices). The diffusion of the dogs into Eurasia caused the extinction of almost all the "dog-like" hyenas, while the bone-crushing hyenas survived.
