First, moisten the cotton ball with saline, and then hold it on your dog`s eyelids for a few moments to soften the crusts. Once they`re soft, use the cotton ball to gently wipe the crust away.
Another remedy is saline solution, which is a mix of salt and sterile water. This solution can be used as an eye wash to clear away discharge and cleanse the affected area. Lastly, apple cider vinegar, a go-to household ingredient, with antibacterial and antifungal properties can help combat the infection.
Rinse your dog`s eye and eye area with simple saline solution, which can be purchased from a veterinarian or pharmacy, or made with a teaspoon of salt water in a cup of warm water. Carefully instill into the corner of your dog`s eye and dip a cotton ball in the solution and wipe away discharge from around the eye.
The only safe human eye drops for dogs are saline eye drops and artificial tears. And, even then, you should discuss why you want to use them with your veterinarian before administering the drops. If you just need to flush out your dog`s eyes to remove a crusty discharge, warm tap water will do the trick.
Certain breeds are prone to dog eye discharge.

Poodles and Cocker Spaniels are more prone to blocked tear ducts, too. Usually, these ducts drain the tears from your dog`s eyes out through the nose and back of the throat.

Vaseline- Once your pet`s tears have been cleaned, apply a small amount of Vaseline to the area just under the eye to prevent the tears from sitting in the same area and staining.
Unfortunately, you would be mistaken to think that the same eye drops you use are suitable for dogs. You should not use human eye drops on dogs. If your dog is experiencing eye irritation, contact your vet and take them in to get an eye examination and possibly eye drops that are safe for dogs.
Make a saline solution using 1/4 cup warm water and 1/4 teaspoon of salt. Dip a gauze pad or clean cloth in the solution, and wipe the eye area starting from the snout (corner of eye) outward, toward the ear.
Sterile saline solution

You will need: 1 cup distilled water or reverse-osmosis-filtered water; ½ tsp non-iodized table salt (iodized salt, rock salt and unrefined sea salt are NOT recommended)

Never Use Human Medications for Dogs

Importantly, medication for humans, including eye drops, are generally not the same for dogs. You should never treat your dog using human medication without consulting a pet care specialist first. Using the wrong eye drops could cause significant pain, damage and blindness.

CAUTION: DO NOT USE CONTACT LENS SOLUTION! Contact lens solution contains enzymes that are harmful to the surface of the eye. A clean, warm, wet washcloth, paper towel, or gauze pad can be applied to the eye for 5—15 minutes, 2—4 times daily.
Your dog`s coat is only one part of good grooming hygiene. Eyes and ears require every bit as much attention. It`s a good habit to clean your dog`s eyes with every bath, but you shouldn`t neglect to clean any noticeable discharge from the eyes. Check for redness or other signs of irritation.
Getting rid of dog eye boogers is simple, the best thing to do is clean your dog`s eyes briefly when you both wake up in the morning. You can do this with a damp washcloth or cotton balls. Keeping your dog well groomed and the hair around his eyes regularly trimmed can prevent irritants like dust from accumulating.
Coconut oil can be used as a natural eye drop solution and helps treat various eye issues in both people and pets. Virgin coconut oil (VCO) and MCT oil are excellent for treating dry eye, blepharitis, and conjunctivitis.
The dogs` eyes and ears are the parts of the body that are most prone to infection. Luckily, coconut oil can help here too. If your dog is having an itchy infection of the ear or eye, you can apply coconut oil to the affected area to help ease the inflammation and clear out the infection.
Your dog`s eye infection won`t go away on its own, nor can you treat it from home. Untreated eye infections can spread into both eyes and even cause blindness. In very rare cases, a dog may require surgery for an eye infection.
Black tea contains theaflavins and thearubigins, which are thought to have antimicrobial and anti-inflammatory actions on the body. While not fully proven, these molecules have the potential to aid in mild cases of canine and feline conjunctivitis (a.k.a. pink eye).
Instead of using your bare (dirty) hands, try a clean washcloth with warm water on it. Apply the washcloth to your eyes gently, and most eye crust will dissolve. You might need to leave the washcloth on for a few minutes to completely clear your eye.
Pink eye, or conjunctivitis, is another common cause of crusty eyes. Viral or bacterial infection can cause pink eye. Viral pink eye usually gets better on its own in 1–2 weeks, according to the AAO. However, bacterial pink eye requires antibiotics.
How long does conjunctivitis in dogs last? The duration of clinical signs depends on the underlying cause. With appropriate treatment, bacterial conjunctivitis is usually fully resolved within 5 to 7 days. Viral conjunctivitis can take up to 3 to 4 weeks for full resolution.
Mix a tablespoon of peroxide with an 8 ounce glass of water and dip a cotton ball into the solution for a homemade daily removal concoction, then dab solution on the fur around the eyes before rinsing it off with warm water.
Bicarbonate solution

Mix a teaspoon of sodium bicarbonate (baking soda) in a glass of boiled, cooled water. Keep the solution in a refrigerator and discard after one week. You can use bicarbonate as an eyebath rinse or to clean the eyelids.

Pour 1000 mL (4 cups) of warm water • Add 2 teaspoons of table salt into your container. Measure exact amount of salt to make sure it is correct. Mix until salt is completely dissolved. Label your container.

Q. Crusty stuff on min poodle’s eye. What liquid can I was it out with besides warm water.
16 years old
ANSWER : A. Warm distilled water will be the best thing to use near your pets eyes.

Q. Weak, discharge from eyes, swelling on right eye, does not want to open eyes. What is wrong?
ANSWER : A. If the discharge from the eye is green or yellow in color, it can indicate a secondary infection. Swollen eyes can be caused by a number of things ranging from allergies to infections, to injury to the eye itself or surrounding areas.

It is best to have your pet’s eye examined by your local vet. They will most likely wish to place a stain in the eye that can check for damage such as cuts or scratches. An ointment can then be given to help reduce inflammation, pain and take care of infection.

Until you can get to the vet, be sure to not let your pet scratch or paw at their eye as this can make things worse. You can also use a warm wet washcloth to gently remove any debris and allow the eye to open some, providing relief. However, if symptoms worsen, or the swelling travels to the face, head or neck, it may indicate a serious allergic reaction which should be treated immediately.

Q. My dog got into a fight with a cat. I think the cat scratch her eye. I clean it out with water. I have gentak can I put that in there?
ANSWER : A. It is best NOT to place anything in the eye unless specifically instructed to do so by your vet as it can cause more damage to the eye. As cat scratches and bites can easily become infected and the eye is a very sensitive area, it is best to schedule a veterinary appointment as soon as possible to have the eye examined. Your vet can place a fluorescent stain in the eye to check the extent of the damage and can then give you a pet-safe medication to place in it as needed to help it heal. Until you can get to the vet, it is best to keep the eye clean of debris and discharge with a warm wet washcloth, and to prevent your dog from scratching or clawing at the eye with the use of an Elizabethan (cone) collar.

Q. One eye is more red than the other. Last night he was pawing at it,today, he isn’t. Should I bring him to the vet?
ANSWER : A. Sounds possible that he had some irritation to the eye that is at least not itchy anymore. You can do either, having it checked now to confirm mild irritation, potentially due to debris or a topical irritant to the eye; or you can flush the eye with sterile saline eye wash (over the counter) using care not to poke or prod the eye and see if the irritation goes away on its own within the next 24 hrs. It has shown improvement already it appears, however if it is not cleared up and your pet seems irritated by it AT ALL, then it should be looked at by a vet and tested for a possible corneal scratch or ulcer. These can cause redness of the eye, eye discharge and pawing at the face. They are usually treated by prescription only topical eye antibiotic ointment and generally do very well after treatment.

Q. I was told by my vet that my dogs cherry eye was caused by something hitting his eye when he was poking around under a bush. I was told surgery needed
ANSWER : A. Prolapsed gland of the eyelid refers to a pink mass protruding from the animal’s eyelid; it is also called a “cherry eye.” Normally, the gland is anchored by an attachment made up of fibrous material. The most common sign of “cherry eye” is an oval mass protruding from the dogs’s third eyelid. It can occur in one or both eyes, and may be accompanied by swelling and irritation. He may have acquired it by getting an injury to his eye but this isn’t the case sometimes. Sometimes there is a weakness in the fibrous attachment.

The veterinarian will review the mass in the dog’s third eyelid and determine if there is an underlying cause for the condition. The diagnosis of the prolapsed gland could be scrolled or everted cartilage in the third eyelid, abnormal cells in the third eye, or a prolapse of fat in the dog’s eye.

Treatment often includes surgical replacement of the gland in the dog’s eye, or removal of the entire gland if the condition is severe. Conversely, if medications are recommended, they are typically topical anti-inflammatory drugs that are effective in reducing swelling.

Q. My dog drinks a lot of water, should I worry?
ANSWER : A. Firstly, you should quantify if your dog is actually drinking an excessive amount of water. In a 24 hour period, a dog should drink about 1 fluid ounce (or 30mL) per pound of body weight. Therefore, the recommended amount of water intake (in fluid ounces) equals your dog’s weight (in pounds). For example, if your dog weighs 8 pounds, he/she should drink about a cup of water in a 1 hour period. This will be slightly increased if your dog gets a lot of physical activity or lives outdoors.

You can measure your dog’s water intake the following way: in the morning, measure a specific amount, a little bit more than you think he/she will drink. 24 hours later, measure the remaining amount. If the amount of water your dog drank is significantly greater than it should be, then you should take your dog to a veterinarian.

Causes for mildly increased water consumption include: food changes, increased ambient and body temperature, increased activity, urinary tract infection, and general illness.

Common causes for greatly increased water consumption include: diabetes, urinary tract infection, kidney disease, steroid use, and other systemic diseases. With large increases in water consumption, you will also usually see increased urination. Please take note of urinary patterns to discuss with your vet. Greatly increased drinking and urination is ALWAYS a reason to see a vet.
