In daily life, pet owners need to pay more attention to the eyes of dogs. When a dog's eyelid is red and swollen, the surface of the eyeball is bloodshot or bleeding, it is called canine pink eye. Dogs often have red bloodshots on the whites of their eyes. Generally, dog owners don’t pay much attention to them. However, if the phenomenon of red eyes persists for several days, a veterinarian should be asked to check with instruments to prevent eye lesions.

1. Eye irritation or allergy.

The dog's eyes are red, possibly due to eye irritation. When dogs are playing, if they are not careful, their eyes will become red when they are irritated.

For example: When the dog is playing on the grass, the eyes are pricked by the grass, causing the eyes to be irritated and congested; when taking a bath, the bath water accidentally flows into the dog's eyes, causing the eyes to be irritated. The above conditions are all causes of red eyes in dogs. If it is caused by these reasons, pet owners should not be nervous. As long as the dog rests well, it will be fine in a few days and does not require treatment.

In addition, it is normal for dogs to have slight congestion of the eyelids when they are exercising, training, or even excited.

2. The eye hygiene is not done well, resulting in inflammation.

When a dog's eyelid is red and swollen, the surface of the eyeball is bloodshot or bleeding, it is called canine pink eye. Red eye in dogs is a symptom that can be easily observed by dog owners. There are many causes of red eye, including blepharitis, conjunctivitis, keratitis, scleritis, anterior chamber inflammation, glaucoma, and anterior chamber hemorrhage.

The most common cause of conjunctivitis in dogs is ocular abnormalities such as trichiasis, ectropion, dry eye, dust and chemical stimulation. In addition, there are infectious reasons. Staphylococcus and mites bacterial infections are also relatively common.

In the clinical diagnosis of conjunctivitis, the general principle is to carefully examine the eyes after magnification to exclude local causes.

If both eyes are affected and there are abnormalities in other organs, systemic underlying disease should be considered. If only one eye is affected, exclude foreign bodies, dacryocystitis, and at the same time know which deep eye diseases can cause inflammation of the conjunctiva.

a. Clean the eyes Gently wipe the eye and eyelid secretions away, then use an eye wash to rinse off any remaining eye secretions.

b. Avoid sunlight: UV rays are irritating and can irritate the conjunctiva.

Used in every case of suspected dry eye, or when conjunctival abnormalities are present (conjunctival hyperemia, eyelid abnormalities, etc.). Antibacterial and anti-inflammatory eye drops can be mixed with lubricating eye drops.

a. Topical antibiotics may be helpful for recovery.

b. Antibiotic eye ointment: use 3-4 times a day for 5-7 days.
