If you suspect your horse has canker in its ears, please contact your veterinarian immediately. They can properly diagnose the condition and recommend the best course of treatment.
However, I can provide some general information about canker in horses:
* Canker is a bacterial infection that affects the tissues of the ear canal, potentially causing inflammation, pain, and discharge.
* It can be very painful for the horse.
* Prompt treatment is essential to prevent the infection from spreading and worsening.
Here's what you can do:
1. Observe your horse's behavior. Is it shaking its head, scratching its ears, or showing signs of discomfort?
2. Check for any signs of discharge or redness inside the ear.
3. Contact your veterinarian immediately. They can examine your horse and determine the best course of action.
Remember, it's crucial to rely on a qualified veterinarian for diagnosis and treatment of any medical conditions in your horse.
