There may be many reasons for pimples on the corners of dogs' eyes, such as infection, inflammation, allergies, tumors, etc. So whether it can heal itself depends on the situation. If a pimple is caused by a minor infection or inflammation, it is possible to heal on its own with proper care and observation.

The most important thing to note is that if the pimples are caused by tumors, they will heal on their own. The possibility is very small. Tumors may be benign or malignant and need to be determined through examination and diagnosis by a veterinarian. If a tumor is diagnosed, appropriate treatment will be required based on the veterinarian's recommendations, which may include surgery, medication, etc.
