How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Cover the eye with a damp, clean cloth and bandage it loosely to the head. If you can do it quickly, soak the cloth in warm, salty water or a supersaturated sugar solution to help preserve the eye. Get immediate veterinary attention, keeping the dog as quiet and calm as possible.
Erosion of a few layers of the epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is deeper erosion through the entire epithelium and into the stroma. With a corneal ulcer, fluid accumulates in the stroma, giving a cloudy appearance to the eye.
Nuclear sclerosis usually gives your dog`s eyes a cloudy, bluish discoloration, unlike cataracts, which are white and opaque. More important, nuclear sclerosis (also called lenticular sclerosis) does not significantly diminish your dog`s vision the way cataracts do. It tends to affect both eyes at the same time.
There are several reasons why a dog might experience cloudy eyes, including corneal ulcers, corneal trauma, glaucoma, dry eye, corneal degeneration (breakdown of the cornea), dystrophy (abnormal cornea formation) or cholesterol deposits in the cornea.
Most corneal abrasions and eye scratches are minor and will heal on their own in a few days, but it`s always a good idea to see a doctor for an eye exam.
Can a dog eye injury heal on its own? In some cases, yes. Certain injuries like corneal ulcers or scratches may heal on their own, but they still need to be assessed by a vet. If an infection develops, or there is foreign material like a grass seed still lodged within the eye, the consequences can be severe.
An injured cornea will include a lot of discomfort for a dog and could result in a canine scratching at their eye even more. The scratch could lead to more serious issues like a corneal ulcer. A vet can examine eyes and decide on treatment options.
Trauma. Corneal trauma is another common cause of corneal edema and a blue eye in dogs. Trauma can occur from a foreign body such as a plant or branch, or it can be the result of an injury during rough play.
Blue eyes in dogs are completely normal and aren`t linked with any health problems. Certain breeds, such as Siberian husky, carry a gene for blue eyes and don`t experience any vision defects because of it. However, eye diseases such as cataracts and glaucoma can change a dog`s eye color to blue gradually.
There are types of diseases that can cause a change in eye color. Cataracts are a common cause, mainly in dogs and can cause changes either because of congenital reasons or because of diabetes. “Other changes of eye color can be due to conditions of the cornea or infections of the iris,” she said.
Cloudy eyes in dogs can be associated with different eye problems, or it can just be a sign of your dog aging. In most cases, it is linked to a natural aging process in middle-aged to senior dogs (typically over six years of age). In some cases, the condition can be painful and challenging to treat.
If the corneal abrasion is minor, most people will feel better in 24 to 48 hours. The cells in that part of the eye reproduce very quickly. Larger scrapes may take longer to heal. If your eye isn`t feeling better after 24 hours, you should contact your optometrist or ophthalmologist.
The fact is that if your dog is experiencing any eye sensitivity, irritation, or pain it`s time to head to your vet. Your veterinarian will be able to conduct a thorough eye exam to determine the cause of your pup`s symptoms and provide effective treatment to help your dog`s eyes feel better.
Signs that a dog eye ulcer is healing include decreased redness and squinting, and the dog just seems more comfortable. Additional signs a dog eye ulcer is healing include: Third eyelid goes back down. Eye no longer looks white.
Eye infections rarely get better on their own. Your pet needs to see a veterinarian right away. Not only can your pet go blind, but eye infections are very painful. Prompt treatment can greatly reduce the pain and improve your pet`s chances of retaining full vision.
The vast majority of corneal injuries are fairly minor and respond really well to simple treatment. This usually involves a short course of antibiotic eye drops and some painkillers for a week or so.
Look out for the following after an eye injury:

Trouble seeing. Irregular pupil dilation or shape. Blood in the eye. Tears and cuts in the eyelid.

Blind dogs and cats adapt well to a life without sight. Loss of vision and struggling to see does not negatively impact a blind pet`s quality of life. A blind pet may lose their eyesight, but they can still run, play, and enjoy their life.
Small dogs are considered senior citizens of the canine community when they reach 11-12 years of age. Their medium-sized friends become seniors at 10 years of age. Their larger-sized colleagues are seniors at 8 years of age. And, finally, their giant-breed counterparts are seniors at 7 years old.
Symptoms of Corneal Ulcers in Pets

The white part of the eye, called the sclera, may become bloodshot, and the conjunctiva around the eye may swell up depending on the extent of the injury. The cornea will appear cloudy and will sometimes have a pinpoint white lesion in the middle where the ulceration is.

A dog with a black eye will likely be showing signs that it is in pain, such as pulling back from being touched and pawing at the affected area. The eye itself may be red, and the surrounding tissue can swell to the point where the eye is no longer visible. Any blunt trauma to the face can result in a black eye.
According to Irizarry, the mutation of the ALX4 gene in Siberian huskies seems to result in decreased pigment production in the eye. The lack of pigment causes the eye to appear blue.
That said, the trait is still quite rare. In our DNA testing, we`ve found only about 5% of dogs to have the blue eye variant. Genetic variants may cause only one eye to be blue.
Most dogs have brown to golden eyes. But what dog breeds have blue eyes? Blue eyes can be found in a few breeds, most notably the Siberian Husky, Alaskan Klee Kai, Dalmatian, and Australian Shepherd.

Q. I have a 1 year old Siberian Husky with blue eyes. I accidentally poked him in they eye and now his eye is cloudy. What to do?
ANSWER : A. You should take him to your vets without delay. Cloudy eye means corneal involvement (scratch, wound or corneal ulceration) which can be serious if left untreated.

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. 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. 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 pet is suffering eyes discharge, what should I do?
ANSWER : A. Mucus, yellow-green pus, or a watery eye discharge can all be signs of conjunctivitis, which is inflammation of the lining of your dog’s eye.

There is a wide range of causes for conjunctivitis, from allergies, injury, birth defects, and tear duct problems, to foreign bodies, dry eye syndrome, infections or even tumors.

Other signs of conjunctivitis include excessive blinking or keeping the eye closed, squinting and pawing at the eyes.

Treatment of this condition depends on the underlying cause. In most of the cases cleaning, soothing the eye and applying antibiotics eye drops suffice but is some instances further investigation is required to establish the cause of the excessive eye discharge, and this should be performed by a veterinarian.

Q. What can be given to dogs to stop the brown draining around dogs eyes? I was told tetracycline would work.
ANSWER : A. Eye leakage is normal in some breeds of dogs, especially those that are more “bug-eyed” types. This eye leakage is just normal tears coming from the eye which can stain lighter colored coats. Unless there is an infection it does not need to be treated with antibiotics. Signs of infection usually include drainage that is thick or goopy and is yellow or greenish in color. Dogs with infections may also want to keep the eye closed, or may paw and scratch at it.

For plain tear-staining. Tear-stain wipes can be used around the eyes to remove the stain and bring the coat back to natural color. If infection is suspected, it is best to have your vet take a look at the eye prior to placing any medications in it.
