No, no. It was finally determined that it was something about the wild cherry tree. (Forgot what exactly) I followed this story for a while because I have some wild cherry trees on my property.
That said. We had a number of horses in the area die from EEE last year. (There is a vaccine for EEE)
Now, what I'm trying to find out is: can dogs get WNV?
At first blush it would seem that mosquitoes can bite dogs, cats, horses, cattle, sheep and goats almost as easily as man. Bites would be first to ears, noses, and places of exposed skin. Perhaps you can use a Deet product on your dogs ears and exposed parts like Off or Repel or something. I put it on our dog occasionally when the bugs are bad, just for his comfort.
