Red ears
If your puppy's ears appear red and inflamed, it could be indicative of an ear infection. Your puppy may start scratching, petting, and shaking his head frequently to try to relieve the discomfort.
Odorsome ears
Some dogs, especially those with droopy ears or narrowing canals, are more prone to developing ear infections. These characteristics create an environment inside the ear where bacteria and yeast can thrive. Common symptoms of an ear infection in dogs include red, irritated skin and a smelly ear discharge. If your puppy's infection is caused by fungus or yeast, you may also observe pasty, smelly discharge from the ears.
Discharge from the ears
Ear discharge is often indicative of an ear infection, although it could also be a sign of other problems such as ear mites or fungal infections. Infections of the external ear canal (external ear infection) are caused by an abnormal buildup of bacteria, yeast, or fungi. Dogs with allergies, endocrine disorders and tumors of this canal are especially prone to developing external ear infections.
Sore ears
An ear infection can be extremely painful for your puppy, so it's essential to have them checked by a vet if you suspect they have one. This will help relieve discomfort, prevent the infection from spreading further, and avoid more serious problems. Cleaning your dog's ears regularly is a wise idea to prevent dirt, debris and wax buildup. This reduces the chance of irritation or an ear infection due to ear wax buildup.
