You may notice that your dog’s eyes do not trace objects together and one or both are involuntarily going in different directions. Your dog will most likely not be in any pain or discomfort due to the strabismus, however underlying causes of his crossed eyes may cause him some other concerns or signs. 

While the condition is rare in dogs, strabismus is more common in certain breeds of dogs. The one thing to know right away is that while it may appear to be a large concern, there is no evidence that your dog will be in any pain or that his quality of life will suffer, depending on the cause of the problem.  

Strabismus is any abnormal position of your dog’s eyes. Typically, your dog’s eyes move together – left, right, up and down. This condition is more commonly known as lazy eye.

The only sign of this condition that you will notice is your dog’s eyes are looking in different directions. He may struggle to focus both eyes on the same item at one time. He may be in control of one eye, however, the other eye may deviate in a non-typical direction. One or both of his eyes may be impacted by strabismus. If his eye or eyes turn towards his nose he may be diagnosed as being cross eyed, and on the other end, if his eyes turn away from his nose it is called divergent strabismus. 

There are a few possible causes for your dog to develop strabismus. They are inherited/congenital cause, result of injury, or problems with his vestibular system (inner ear). 

Certain breeds are prone to developing strabismus. These breeds inherit the weak muscles that cause the traveling eye and may have them at birth.

There is some evidence that the following breeds are also at a higher risk of developing strabismus:

Injuries caused to your dog’s eyes, head or the like that have injured his nerves in his eyes can result in a strabismus as a side effect afterward.

If your dog has a problem with his vestibular system, this can also result in a strabismus. His vestibular system, just like that in humans, has a primary function of promoting balance. 

If you suspect your dog may be suffering from strabismus and are concerned, a visit to his veterinarian will be necessary. Prior to your visit, it will be important to note and identify any signs you may have been noticing in recent days, weeks, or months that may have concerned you. It will also be important to share with the veterinarian if there have been any accidents or trauma to your dog to explain his new signs.

Your veterinarian will want to perform a physical examination of your companion and will want to evaluate his eyes to determine what could be the cause of his eyes looking in different directions. Your veterinarian may want to run blood tests to rule out any underlying causes of the strabismus as well. Testing could also involve MRI or X-rays to see any further damage and underlying issues. However, there is not a standard test performed to formally diagnose strabismus. Rather your veterinarian will diagnose by elimination of other possible causes of the presenting problem.

Treatment for your dog will largely depend on the cause of his strabismus. Whether it is an inherited condition, or whether it was acquired via injury or a nerve disease, will determine the course of action taken to help him. 

If your dog is found to have inherited strabismus and there are no other underlying conditions or trauma that could have caused his signs, your veterinarian may not recommend any treatment. It has been found that if your dog has the inherited strabismus no treatment is necessary and his quality of life should not suffer. Your dog will be able to adjust and you may be given exercises to try and strengthen his eye muscles.

These exercises involve having your dog track your finger as you hold it in front of his face and slowly move it in towards his nose. It can help increase his muscle strength in the weak eye but will take time. However, it is considered a cosmetic concern when it is inherited so there are no long-term effects to be concerned with. 

If your dog acquired the strabismus with no injury or trauma known, your veterinarian will treat the underlying issue. Some of these issues can be inner ear injuries or infections which would be treated accordingly. Other issues can be nerve damage to his eyes which may need to be treated with anti-inflammatory medications. 

If your pet started getting his strabismus upon an injury, any immediate medical needs will be addressed first. After your dog is stabilized, your veterinarian will then discuss any further options for his strabismus if necessary. Medication can be prescribed for your dog if he is experiencing nausea due to his injuries or vestibular problems. A large part of treating his strabismus will be time and patience. 

Since most vestibular diseases are not life threatening to your dog, he will most likely compensate for his new signs but this will be where time and patience come into play. You will need to give him some time to adjust to his new world. Carrying him can cause him to take longer to recover from his signs and should be avoided for a while. Lastly, providing him with a lot of light so that he can use that for his own cues of distance, position and more will benefit his recovery as well.

Recovery time can be as little as 3 days and up to 14 days before he is adapting or getting back to his normal self. Once again if it is the result of an injury, his recovery time will be dependent on the severity of his injury. If it is inherited there will be no recovery time as your dog will adapt to this on his own.

Follow up will be discussed with your veterinarian and will depend on your dog’s needs. If there is any type of treatment in place via medication, she may ask you to come back or check in with them after a certain period. Your veterinarian will ask you to keep an eye on him for any further or new symptoms to be aware of.

Providing your dog with space and some possible adaptations as recommended by your veterinarian will be beneficial to him. He should make a full recovery and will adapt to his new sensory input within a few weeks. Keeping him safe and his environment comfortable will help with his recovery as well.
