It's crucial to contact your veterinarian immediately. They can properly diagnose the cause and recommend the best treatment for your puppy.
Here are some potential causes of puffy eyes and discharge in puppies:
* Conjunctivitis: This is a common eye infection, often caused by bacteria or viruses.
* Allergies: Allergens like pollen, dust, and food can trigger eye irritation and discharge.
* Entropion: This is a condition where the eyelid rolls inward, causing the eyelashes to rub against the cornea.
* Blocked tear ducts: This can lead to excessive tearing and discharge.
* Foreign object: A small object in the eye can cause irritation and swelling.
* More serious conditions: In some cases, puffy eyes and discharge could indicate a more serious condition like a corneal ulcer or glaucoma.
Please don't hesitate to contact your veterinarian for a proper diagnosis and treatment plan.
