New canine distemper outbreak in Texas

There is a mortality rate but it's really hard to establish a reasonable number because most infected are the very young and dogs passing through shelters. Those individuals are seldom treated and are euthanized so establishing a true mortality figure is difficult.

Dogs do survive but often have life long issues either neurological tics, vestibular and/or "hard pad" disease. The hard pad is mostly observed as increased tissue (kind of like a callous) on the nose and pads of the feet.
