Dogs are considered man's best friend, so when your pet is feeling sick, you will want to do anything possible to help it feel better. Just like humans, dogs can catch viruses. These viruses manifest in runny noses, sneezing, coughing and watery eyes. Often, time is the only remedy, and within a week or two your canine will be back to normal. In the meantime, if a cold has traveled to the dog's eyes, there are a few things you can try to help your dog feel better.
Clean the fur around the dog's eye. Soak a washcloth in warm water and then squeeze it out so it is damp instead of wet. Gently wipe the fur surrounding the eye to remove any dried discharge.
Lift the dog's upper eyelid gently while tipping its head back. Apply a few drops of eye wash into the inner corner of the dog's eye. Release the eyelid so the dog can blink, which spreads the eye wash over the entire eye.
Place a few drops of artificial tears into the dog's eye if the discharge seems sticky. This type of discharge indicates dry eye, which makes the eye more susceptible to viruses and dirt.
Call your vet if the eye condition does not improve in two or three days. Your dog may need antibiotic drops if it is an infection or an antihistamine if the eye is being affected by allergies.
