Is my beagle puppy's scratching and red, gooey ears an infection?

Buddy looks to have an ear infection and the ear looks very inflamed. Ear infections need the attention of a veterinarian. There are several different types of infection and the doctor will perform a simple diagnostic to know what type of medication to use. The skin rash and the ear infection could be related although beagles are a breed prone to ear infections due to the heavy, drop ears. I recommend to pick up an ear cleaner at the veterinarian’s office and stay on a regiment of routine ear cleaning after the ear infection is cleared.
If this is the first time he has had any issues, he will likely be treated symptomatically. If the problems come back then start looking for an underlying allergy as the cause. Ear infections can get worse quickly and they can become painful so it’s best to try to get this taken care of today. I hope but he starts feeling better quickly.
