You have every right to expect at least a response from them. I'm very sorry for your loss, & I hope they get back in touch. Contact them again, maybe with a statement from the vet, explaining possible paths of transmission?
We have a white poodle too, & twice a week showers are REALLY bad for dog skin.
One reason she gets 'stinky' so fast is because you are washing her skins natural oils off so often they are over producing.
Once every 2 weeks would be max in my opinion...
Btw, we have cows, chickens & puddles...
CWD are a lot of work. Not that that is bad, just a factor to consider. They also need a lot of room.
I just got a tiny little crested hatchling, & I am totally in love already :)
