Seems UC Davis in California is researching this... it is genetic so I would advise notifying the breeder. Occurs more commonly in horses... they have a DNA test ( don't know if it works for dogs?) UC Davis is collecting samples for their research... From what I've read it is mostly loss of balance and coordination, and dogs will need assistance with stairs and such... no mention of aggression or putting them down though.
But, yes, best to wait for a definitive diagnosis... |
