Treating Kennel Cough in Dogs and When Eye Drops Are Safe
Most cases of kennel cough resolve on their own with rest and supportive care, but you should call your veterinarian if your dog's cough worsens, lasts more than 1–2 weeks, or is accompanied by fever, lethargy, or difficulty breathing. For dog eye infections, over-the-counter drops are only safe for minor irritations—saline solutions or artificial tears—and human eye drops (especially redness relievers like Visine) can harm your dog; bacterial or viral conjunctivitis usually requires prescription medication from a vet. The key is knowing when home care is enough and when professional intervention is necessary to prevent complications like pneumonia or permanent eye damage.
When Kennel Cough Stays Mild vs. When It Needs Medication
Kennel cough (Canine Infectious Respiratory Disease Complex, or CIRDC) is typically self-limiting in healthy adult dogs. The hallmark symptom is a dry, hacking cough that sometimes sounds like a goose honk. In mild cases, your dog remains active, eats normally, and has no fever. These cases often improve within 1–2 weeks with supportive care alone—no antibiotics needed.
Supportive care at home includes:
-
Rest: Limit exercise and prevent excessive barking to reduce throat irritation
-
Humid air: Use a humidifier or bring your dog into a steamy bathroom for 10–15 minutes to loosen mucus
-
Hydration: Ensure fresh water is always available; warm chicken broth can encourage drinking
-
Harness instead of collar: Reduce pressure on the trachea during coughing fits
-
Isolation: Keep your dog away from other dogs for at least 10–14 days to prevent spread
Antibiotics are only appropriate when there's evidence of secondary bacterial infection or high risk of pneumonia. Common antibiotics include amoxicillin/clavulanic acid, but these should only be prescribed by a veterinarian. Cough suppressants may be used for comfort but are contraindicated if pneumonia is present.
Why Most Dog Eye Infections Need Prescription Drops, Not OTC
Conjunctivitis (pink eye) in dogs has multiple causes—infections (bacterial or viral), allergies, injury, or underlying health issues—and treatment depends entirely on the root cause. Unlike kennel cough, which is often self-limiting, eye infections rarely resolve properly without correct diagnosis and targeted treatment.
The only over-the-counter eye products generally safe for dogs are saline solutions and artificial tears for minor irritations or debris removal. Even these should be used only after discussing with your veterinarian.
Human eye drops are dangerous for dogs. Redness-relief drops (like Visine) contain decongestants that can be toxic. Allergy eye drops meant for humans often contain preservatives or active ingredients that irritate canine eyes.
Most infectious conjunctivitis requires:
-
Prescription antibiotic drops or ointment for bacterial infections
-
Antiviral medication in severe viral cases
-
Steroid drops (only under vet supervision) for inflammation when infection is ruled out
-
Antihistamine drops for allergic conjunctivitis, though these are less common in dogs
notes that most allergic dogs present with skin itching rather than eye inflammation, and when allergic conjunctivitis does occur, prescription drops formulated for veterinary use are most effective.
Red Flags That Mean Stop Home Care and See a Vet Immediately
For kennel cough, contact your veterinarian if:
For eye issues, seek veterinary care immediately if you see:
-
Yellow or green discharge that persists
Your vet may perform a conjunctival swab, fluorescein stain (to check for corneal ulcers), or other diagnostics to determine the cause and appropriate treatment.
emphasizes: "Don't attempt to treat your dog's eye infection on your own with human medications or with medications previously prescribed to your dog."
How to Safely Administer Eye Drops When Your Vet Prescribes Them
If your veterinarian prescribes eye drops, proper administration ensures the medication works effectively and reduces stress for both you and your dog.
Steps for giving dog eye drops:
-
Wash your hands thoroughly before and after
-
Clean the area around your dog's eye with a warm, wet washcloth to remove discharge
-
Restrain gently—cradle your dog's head or have someone help hold them steady
-
Hold the bottle with your dominant hand, thumb and index finger gripping it
-
Pull down the lower lid with your opposite thumb (other fingers support the jaw)
-
Position close but don't touch the eye with the dropper
-
Squeeze prescribed amount into the center of the eye
-
Let your dog blink naturally to spread the medication
-
Reward with praise or a treat to create positive association
Keep an Elizabethan collar (cone) on your dog if they tend to rub their eyes, which can cause further trauma.
Common Mistakes That Make Kennel Cough or Eye Infections Worse
Several well-intentioned actions can delay recovery or cause harm:
For kennel cough:
-
Using a collar instead of a harness—pressure on the trachea triggers more coughing
-
Delaying veterinary care when symptoms worsen—pneumonia can develop
-
Not isolating infected dogs—spreads infection to other pets
-
Assuming antibiotics are always needed—most mild cases are viral and won't respond
For eye infections:
-
Using human eye drops—Visine and redness relievers are dangerous
-
Assuming all red eyes are infections—injury, allergies, or glaucoma may require different treatment
-
Stopping medication early when symptoms improve—incomplete treatment leads to recurrence
-
Using old or shared medications—each case needs specific diagnosis
-
Expecting OTC drops to cure infection—most infectious conjunctivitis needs prescription antibiotics
One critical misunderstanding: many pet owners assume that because kennel cough is self-limiting, eye infections are too. This isn't true. While mild kennel cough often resolves with supportive care, eye infections typically require targeted medication to prevent corneal damage or vision loss.

Frequently Asked Questions
Can kennel cough kill my dog?
Kennel cough is rarely fatal in healthy dogs, but severe cases can lead to pneumonia, which can be deadly. Death is uncommon but possible in puppies, seniors, or immunocompromised dogs.
What's the fastest way to cure kennel cough?
Most cases resolve on their own in 1–2 weeks with rest, humid air, and hydration. There's no instant cure—antibiotics only help if a bacterial infection is present, and only a vet can determine this.
Are any human eye drops safe for dogs?
Only saline drops and artificial tears are generally considered safe, and even then only after consulting your veterinarian. Never use Visine or redness-relief drops—they can be toxic.
How long does dog conjunctivitis last without treatment?
Viral conjunctivitis may resolve on its own in a few days to a week, but bacterial conjunctivitis usually requires antibiotics. Without proper treatment, eye infections can lead to corneal ulcers or permanent damage.
When should I isolate my dog with kennel cough?
Isolate your dog from other pets for at least 10–14 days to prevent spread. Kennel cough is highly contagious and spreads easily through close contact or shared items like bowls and toys.
