What the experts say

“Harvest mites can usually be seen with the naked eye, especially if there is lots of them! However, if the mites can’t be seen, or your dog has unusual symptoms, your vet may need to send off some skin scrape samples for analysis.”

If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
