My dog ​​has puffy eyes and scratches a lot: causes

Inflammation of the eyelids is known as blepharitis. We can see that our dog has swollen eyes and scratches a lot. In a bacterial blepharitis, in addition, the eyelids thicken, become red, swollen and may also have scabs. Like blepharitis can be associated with various diseases (demodectic mange, hypothyroidism, etc.), in addition to the discomfort it is causing the dog, we must go to the vet to diagnose any underlying disease and, thus, an effective treatment.

Blepharitis itself is treated with antibiotics that our vet must prescribe. Before applying any medication to the eyes we must clean them, which we can do with a gauze or cotton dipped in physiological serum. Long-term medication may be required. Sometimes the eyelids become swollen suddenly, usually from insect bites or even an allergic reaction to a food. These cases also require veterinary assistance and may be another reason why my dog ​​scratches his eyes so much.

Itching in the dog's eyes from foreign bodies and injuries

Foreign bodies such as seeds or various plant fragments can enter the eyes of dogs and remain attached to the surface of the eye or behind the eyelids. One of the activities that increase the probability of the introduction of particles in the eyes is to allow our dog to travel by car, sticking his head out the window. Walks through dense vegetation are also another risky activity. The presence of a foreign body can explain why a dog scratches its eyes so much, in addition to presenting other symptoms such as tearing, blinking, or discharge. The third eyelid in an attempt to protect the eye. This eyelid, called the nictitating membrane, is located in the inner corner of the eye and is generally only seen on certain occasions, such as the one at hand. Unless we see it very clearly, we must go to the vet to extract the foreign body that is causing the injury. It must be taken into account that elements such as brambles or splinters can pierce the cornea (the transparent part of the eye).

Splashes of chemical agents in the eyes can also explain why our dog scratches his eyes so much. Acids but also soaps, shampoos or insecticides can cause itching and tearing in the dog's eyes, as can toxic fumes. The affected eye or eyes must be washed immediately with cold water or saline solution and the dog must be taken to a veterinary clinic..

Itching in the dog's eyes due to conjunctivitis

Conjunctivitis in dogs is a relatively common condition that consists of inflammation of the conjunctival membrane that covers part of the eyelids and the eyeball. In addition to observing that the dog rubs its eyes, we will be able to see redness and serous discharge, mucoid or purulent. Our veterinarian will be in charge of the treatment because a systemic disease such as distemper or a foreign body could be behind it, in which case it would normally affect only one eye. Depending on the type of discharge we can talk about different conjunctivitis, which can explain why a dog scratches its eyes so much. They are as follows:

  • Serous conjunctivitis: the inflammation is mild and the discharge is clear. This conjunctivitis is what can cause agents such as wind or dust, in addition to allergens.
  • Mucoid conjunctivitis: the nictitating membrane or third eyelid has small glands on its inner side. When they react to an irritating substance or an infection, they end up producing a mucoid discharge that triggers conjunctivitis..
  • Purulent conjunctivitis: it is a serous conjunctivitis that becomes infected by the presence of different bacteria. Thick, crusty secretions occur on the eyelids.

As we have said, if the dog has red and rusty eyes, the vet will look for the underlying cause that has caused the conjunctivitis and, depending on what it is, will prescribe the appropriate treatment, which may include eye drops, ointments or even some ophthalmological intervention. if there are complications. As always, before applying any medication we must clean the eye well with saline solution and gauze or cotton. If our dog has dry scabs we can heat the serum to remove them more easily.

Itchy dog's eyes from a corneal ulcer

A corneal ulcer can be defined as an injury to the cornea, which can be caused by trauma or diseases such as diabetes, hypothyroidism, or Addison's disease. Corneal ulcers are painful, which explains why our dog scratches his eyes or the affected eye so much. They also produce a considerable tearing and photophobia (intolerance to light), which also explains why the dog has closed eyes and blemishes.

It requires veterinary attention, since, without treatment, you could lose your eye. Some ulcers can be seen with the naked eye as a dull, dull area. The veterinarian can confirm its presence by putting a few drops of fluorescein in the eye, since this substance stains them. They are usually treat with antibiotics and / or surgery.

Itching in the dog's eyes due to keratitis

Keratitis is another condition that can affect the cornea. In this case it produces an inflammation that makes it cloudy and causes intense tearing, intolerance to light (photophobia), protrusion of the third eyelid and explain why the dog scratches his eyes so much. There are several types and all are serious, since can lead to blindness. They are as follows:

  • Ulcerative keratitis: This inflammation of the cornea is a consequence of other conditions, such as a corneal ulcer. The cornea begins to appear dull until it becomes cloudy and ends up turning white..
  • Infectious keratitis- Occurs when a bacterial infection complicates another disorder such as corneal ulcer or ulcerative keratitis. It causes a purulent discharge and the eyelids appear swollen. Fungi could also complicate the picture (fungal keratitis).
  • Interstitial keratitis: also known as "blue eye ", as a bluish-white film forms on the eye. The cause is the infectious hepatitis virus.
  • Vascular keratitis: Blood vessels and connective tissue grow into the interior of the eye. This process can sometimes be associated with pigmentary keratitis, in which a deposit of melanin (which is a pigment) occurs in the cornea.

Of course, it requires veterinary assistance and can be treated with drugs and / or surgery..
