Causes of conjunctivitis in dogs:

1. Foreign matter enters the eyes, which is caused by irritation.

2. The dog accidentally hit its eye and was injured.

3. Parasitic infection, allergic irritation, etc. Secondary canine conjunctivitis is caused by infection and lesions in the organs around the eyes. This situation is generally caused by infection with respiratory system diseases, such as canine distemper, mycoplasma, chlamydia, etc., and needs to be sent to the hospital for treatment.

Treatment methods for dog conjunctivitis:

1. When acute conjunctivitis is severely congested, use 3% boric acid solution or 0.1% Rivanol solution to wash eyes and apply cold compresses , apply anti-inflammatory eye ointment 4 times a day. When the pain is severe, 2% cocaine can be used for eye drops. For chronic conjunctivitis, hot compresses can be applied, and concentrated zinc sulfate or silver nitrate solution can be applied locally to the eyes. If the nipple proliferates and forms follicles, crystallized copper sulfate can be used for cauterization.

2. For conjunctivitis complicated by canine distemper and canine infectious hepatitis, chloramphenicol ointment should be applied to the conjunctival sac 1 to 3 times a day on the basis of treating the primary disease. Caused by mycoplasma and chlamydia, choose chloramphenicol eye drops to instill in the eyes, 2 to 3 times a day. Drug selection for bacterial infections should be based on drug susceptibility testing. For fungal conjunctivitis, use amphotericin B125μm, subconjunctival injection every other day, for 2 weeks. This drug is toxic to conjunctival tissue and cannot be used for eye drops.

3. For conjunctivitis caused by physical and chemical factors, the cause should be removed first. If the corneal tissue is not damaged, 0.05% flumetasone eye ointment can be applied in the conjunctival sac, 1 to 3 times a day; when acid or alkali invade, the eyes must be washed thoroughly for 5 to 10 minutes.

4. For conjunctivitis with allergic factors, the allergen should be removed and thimerosal should be instilled in the eyes 5 to 6 times a day. Or put lead sulfate solution into the eyes, 3 to 5 times a day. Use broad-spectrum antibiotics as appropriate.

5. For stubborn purulent conjunctivitis, 1% iodoform ointment should be applied, and procaine penicillin should be used to seal the fundus.
