To clean your dog's eyes crust, you can use a warm cloth, a cotton ball with baby shampoo, or a pet eyewash to soften the boogers and wipe them away. You can also use eye drops to help prevent or treat eye infections. Be gentle and avoid rubbing the eye itself.

Here are the steps you can follow:

1. Start by washing your hands thoroughly.
2. Soak a clean cloth in warm water and wring it out.
3. Hold the cloth against your dog's eye for 30 seconds.
4. Gently wipe away any visible crusted areas around each eye using a cotton ball with baby shampoo or pet eyewash.
5. Use a separate cotton ball for each eye to avoid spreading any infection.
6. If your dog has excessive discharge or redness in their eyes, consult your veterinarian.
