Dog conjunctivitis is caused by bacterial or viral infection and does not spread through the air. However, if you touch your dog's eyes with your hands without washing your hands before touching your own eyes, it may cause infection. Therefore, as long as you wash your hands frequently, pay attention to hygiene, and do not touch the dog's eyes with your hands and then touch your own eyes, you will not be infected. When giving eye drops to your dog, you can wear disposable gloves for prevention.
