Could be dogs don’t become “sick” with Ebola, they’re just carriers, and can remain thus indefinitely.
I am by no means an authority on the topic.
From what I’ve read, that’s the case. Canines seem not to become sick themselves from Ebola, the way raccoons (IIRC) can be carriers for Rabies.
Dogs develop antibodies to the virus. Some believe dog to human infection may be possible. As others have noted repeatedly in other threads, that has not been proven and no confirmed cases exist.
Seems that if the dog has the virus, a lot could be learned from studying it in a properly controlled setting. Examples: does the dog’s saliva include viable virus? Other bodily fluids? Why don’t dogs get sick. Etc.
If the dog doesn’t have the virus, then nothing is served by putting it to sleep.
Like coons are carriers for rabies but most don’t manifest symptoms?
The most recent study showed dogs get ebola, but do not show symptoms. There is no evidence they spread the disease. But the study indicated it was possible. Certainly in the West we treat our dogs differently than in Africa. I have more direct contact with my dog than most members of my family. My dog is always licking my hand or face. If she had ebola, her sloppiness could be fatal.
