Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bruno! The good news is that Demodex isn't contagious to other dogs or people. Also it is super easy to treat now thanks to the new oral flea and tick medications. The once a month Nexgard or Simparica and the every 3 month Bravecto also kill demodex when prescribed at the normal frequency. Personally I wouldn't use any other medication as these are much safer. I would say it will likely take up to 3 months for Bruno to be cured but you will likely see improvement before then. I wish you and Bruno the best!
