Here's what I recommend you do:
1. Contact your veterinarian immediately. They will be able to diagnose the cause of the ear infection and prescribe the appropriate treatment. This may include:
* Cleaning the ear canal.
* Medicated ear drops.
* Oral antibiotics.
* Other medications.
2. Follow your veterinarian's instructions carefully. This is crucial to ensure your dog receives the best possible treatment and a full recovery.
Signs of an ear infection in dogs:
* Head shaking
* Scratching at the ears
* Redness or swelling in the ear flap
* Foul odor coming from the ear
* Ear discharge
* Pain when the ear is touched
Remember, it's important to seek professional veterinary care for your dog's ear infection. They can provide the best and safest treatment for your furry friend.
