The redness of the whites of the dog's eyes may be caused by trauma, foreign objects, and fire. If a dog accidentally touches the eye or touches a sharp object while playing with other dogs, it will cause redness of the eyes, and severe corneal ulcers will lead to corneal perforation. But under normal circumstances, it will not be very obvious. Only in the case of dogs with serious eye diseases and inflammatory infections, the bulbar conjunctiva will become red. If the dog has redness of the bulbar conjunctiva and obvious blood vessels, it is recommended that the owner wear a collar for the dog as soon as possible, and take the dog to the veterinary hospital for medical treatment.

In addition, dog conjunctivitis is accompanied by severe itching Symptoms, so be sure to do a good job of protection to prevent the dog from scratching, thereby causing serious mechanical damage.
