Ear mites are easy treated with products such as Simparica, Nexgard, Bravecto or Credelio. These are by prescription only and can be obtained from your veterinarian. Oftentimes, just one dose of any of the above can resolve ear mite infection. The fleas may be more stubborn. You can give Chaos a dose of CapStar to rapidly kill any adult fleas on him. This medication can be given daily if necessary. Follow up with an oral or topical preventative. Treat monthly for at least 3 consecutive months, preferably year round. Consider "pre-treating" your home with an area treatment, such as Indorex or Knockout ES, to prevent infestation. Most fleas live in the environment and will hop on a dog (or you) only to take a meal. Consider an exam with your veterinarian to diagnose and treat any infection or other underlying conditions.
