My bf's dog is being treated for ear mites, this particular dog seems to be prone to them, and has been treat a couple of times in the past 5 years, his other dog never gets them, well I brought Bailey over to play with the dogs thinking ear mites were not contagious because they never spread to my bf's other dog, but now I think Bailey has caught them. He is shaking his head and scratching

The vet is closed until Monday, Is there anything I can give him to help the itching until he can see a vet? I feel terrible.
