They do not cause pain, but discomfort. In addition, we must know that there are different types, so a veterinarian will tell us if they can withdraw or not.

What are the symptoms of blindness in dogs?

To find out if our dog is going blind or if he is already born that way, we will have to observe if it shows some of these symptoms:

  • Your eyes will be blurred, inflamed, or with color changes.
  • Tears constantly.
  • It crashes into furniture and other objects.
  • He has stopped jumping.
  • He prefers to stay in safe and well-known areas for him.

If we observe that our hairy eyes have some of these changes, we must take it to the vet as soon as possible.

How is blindness treated?

Once we take it to the vet, he will tell us if it can be treated or not, since there are different degrees of blindness. For example, if what you have is cataracts but they have been detected in time, with an operation they can be removed, but if it has been due to a malformation the animal will have to live with it throughout its life.

What are the care of a blind dog?

Caring for a blind dog is no different than caring for a dog that can see. However, Yes, we will have to take some measures to avoid accidents, both inside and outside the home:

  • Have the doors closed at all times, even the one that leads to the balcony.
  • Do not change your feeder, drinking fountain or bed, unless it is on the top floor, in which case we will lower them and guide you with treats to them.
  • Keep away from him anything that may be dangerous.

Blindness in old dogs

The main problem of blindness in old dogs is because of the cataracts, which in some cases can also occur in puppies and young hairy, although it is not so frequent. Cataracts are a problem of your lens that becomes opaque. To know that you are going blind because of the falls you just have to look at their eyes.

As the days progress they will become whitish. This is a degenerative disease that is getting worse and worse, so if you don't take action on the matter, you will end up being totally blind. To correct cataracts there are no home remedies that are worthwhile, it is necessary to resort to surgical intervention, do not worry, it is simple and has an easy recovery.

Conjunctivitis and lesions in dogs

Conjunctivitis in dogs is a very common condition. There are several types and the most common are those that have a bacterial origin. They usually start first in one eye, which gradually closes because it itches and then passes to the other. When the disease progresses, it begins to secrete pus that materializes with yellow and green legañas.

If left untreated, you may lose sight, but this is not the worst of your problems. Conjunctivitis is a disease that we could classify as ‘opportunistic’, that is, take advantage of the opportunity in which your dog is weaker to infect it, which means that it may be suffering from a worse disease.

To know that you have conjunctivitis you just have to look at their eyes. If you have them covered with scum, you will obviously not be able to see and you will be having a hard time, too.

Blindness due to an injury

Cataracts and conjunctivitis are frequent and we have to be prevented for them, but the most common reason why your dog may have vision problems is by hurting his eyes. And how can damage be done to them? For two factors. The first is that he is very adventurous, playful and explorer, so he sure loves to run and run through the bushes.

This is a danger, because a bramble could scratch your eyes and hurt your vision through an infection that, if not controlled, could blind your vision. Another reason is that you don't spend enough time cleaning your eyes. A rest or a sand scoop could also scratch you. If your dog has bangs, It is a good idea to remove it because a lot of fat accumulates there that nothing is going well for cleaning your corneas.

My dog ​​is going blind because of diabetes

Blindness is one of the complications that could occur in case of diabetes. This disease is usually typical of very sedentary and obese dogs, one of the possible symptoms that warn us of this disease is an increase in daily water intake.

Against diabetes, you have to go to the vet to get a special diet for him and offer a routine with healthy habits. In any of these cases, you will know that he is going blind because he is not able to distinguish you until he is very close to you. You will also notice him disoriented and scared, he will hit the walls of your house and against the legs of the tables.

What to do if my dog ​​is going blind

The first thing you have to do is determine the reason for your blindness with a specialist and proceed to apply the appropriate treatment. On top of that, you have to adapt your home to your new needs. Clear your usual passageways from obstacles, remove any furniture with sharp areas and be especially affectionate with it. Do not be angry because you are losing faculties, on the contrary, be more understanding than ever.

That a dog goes blind does not mean that it will lose quality of life, it still has its nose, which is, along with its mouth, its main source for obtaining information from the world.

Uveitis - The inflammation of the eye

There are many reasons that can cause blindness in the dog. Sometimes we talk about a relatively normal sign in dogs that reach old age, however, it can also be a symptom of a more serious secondary disease, which goes beyond blindness, such as a kidney failure, in the case of the appearance of chronic kidney disease, which causes a deficiency in metabolism. In this case blindness would be an inevitable consequence.

Because the causes of blindness in dogs can be very variable, ideally conduct a proper veterinary evaluation. Remember that some systemic diseases such as Ehrlichiosis, Babesiosis, Toxoplasmosis, Leptospirosis, Leishmaniasis and many others can cause blindness.

Why does my dog ​​get a blue eye?

The eyes are responsible, in addition to capturing the image and transmitting it to the brain, for the control of the passage of light, as well as other functions. It is important to note that a slight change can damage the eyes, sometimes permanently, leaving the animal blind.

When the dog shows a blue eye, we are not necessarily talking about blindness, however, if nothing is done to treat it, blindness may appear irreversibly at the end. Bluish color, as well as any other color change, indicates an inflammation of the eye layer (anatomically we talk about vascular tunic) and that is when we talk about uveitis in dogs.

Uveitis may be caused by bacterial infections, viral infections, trauma or lack of tear production, which cause dryness in the cornea and subsequent inflammation of the eye. It usually affects only one eye and if it is treated on time it doesn't have to cause blindness or leave the animal with sequels. The veterinary visit is required to start a successful treatment.

Waterfalls - The opac>

There are certain races, such as the golden retriever, the schnauzer, the yorkshire terrier or the English cocker spaniel, who are more likely to develop cataracts. However, it should be noted that this pathology can also affect all dogs, including mongrels, and other animals, such as cats.

Why does my dog ​​have white eyes?

When we observe that the cat's eyes are turning white, it means that we can be in the presence of cataracts in the dog. Cataracts do not appear suddenly, but develop gradually, so we will observe that the dog's eyes gradually become white.

It is not always easy to detect, since at first we will only observe the opacity layer when it comes into contact with the light, however, when it advances, we can detect that it is becoming thicker. As the disease progresses the eye becomes completely white and that is when the dog goes blind.

As with uveitis, this disease can affect only one eye, or show in both. Contrary to popular belief, cataracts do not cause pain in the animal, but they can be a nuisance. In addition, there are different types of cataracts, so you should perform a good veterinary evaluation that allows us to know if it is cataract irreversible or not.

The development of catatas may be related to certain pathologies, such as Cushing's disease, diabetes mellitus or hypertension. Avoid using drugs or eye drops for human use, as that can aggravate the problem.

What happens when a puppy was born blind?

Sometimes the puppies they can be born blind due to a malformation, but it may also be due to the cells that capture the images in the eyes. In this case the puppy does not show any obvious symptoms, which causes the owners not to notice, since a puppy adapts better to the environment, thanks to the senses of smell and hearing, which develop much more.

There are many causes, such as negative prenatal conditions, difficulty in childbirth, malnutrition or pathologies suffered by the mother. The hereditary diseases As diabetes can also be a cause.

  • It can also show constant tearing and purulent secretion.
  • It bumps into furniture and objects, from time to time or constantly.
  • Avoid jumping that you used to do easily.

As with humans, cataracts, for example, can be treated depending on the stage of development they are in.
