FFS. All coronaviruses wander around all species all the time. They mutate and cross from one species to another. Every so often, a particularly virulent, pathogenic and contagious one arises that can pass from human to human and we get our pandemics.
This one is ultra-nasty, so I guess it's no surprise it's jumping from us to our dogs and other species we are close to. But that doesn't mean it can yet pass dog to dog, which is the only thing that would increase human's risk from it.
This news does however mean that if I ever do decide I can safely visit my folks (who are in isolation now, with my sister keeping herself and her husband as locked down as possible too so she can help them with it all), then my sister will say I can't bring my dog into their house
But Mum really loves to see the dog, so perhaps I will have to make sure Dot doesn't play with other dogs, so she's been isolated too :/ And as Dot is a complete fruit loop, I don't let other people fuss her anyway, so she won't have picked it up from other humans,
