Collie Eye Anomaly in Dogs: Symptoms, Causes, Treatments


Collie Eye Anomaly (CEA) is a gene problem common in some dog breeds. Border Collies, Australian Shepherds, Rough Collies, and Shetland Sheepdogs often have it. It comes from a bad gene on chromosome 37. The signs are small or foggy eyes. But, these can be hard to spot until the dog starts losing sight. Some dogs may even go blind.

To catch it early, dogs need regular eye checks. This helps improve their life. Bad breeding can make this eye problem more common. Genetic tests can find these bad genes. They are key in managing this health problem. It also helps make future generations healthier.

Treatment can be vet care, changes at home, or surgery for bad cases. More learning about this topic can help prevent it. It also helps to understand living with a dog that can’t see well. Regular checks at the vet are very important.

Key Takeaways

  • Collie Eye Anomaly is a gene problem often seen in Border Collies. It’s due to a mistake on chromosome 37.
  • This condition can cause smaller or foggy eyes. Yet, it’s tough to spot until the dog can’t see.
  • Regular eye check-ups are key to catch it early and make the dog’s life better.
  • Options for care might include a vet’s help, changes at home for vision loss, and even surgery in tough cases.
  • Tests for genes and smart breeding can help reduce this issue in future dog families.

Understanding Collie Eye Anomaly

Collie Eye Anomaly is an eye problem in some dogs. It’s common in breeds like Border Collies, Australian Shepherds, Rough Collies, and Shetland Sheepdogs. It’s caused by a fault on chromosome 37.

We all need to understand and tackle this together. Genetic testing can help us here. This test can find dogs that carry this defect. It helps us make good choices when breeding. Sadly, this issue is common due to unchecked breeding practices.

Using genetic testing can lower the number of cases. It can make future generations of these breeds healthier. We must join forces to fight this issue. It’s key to make sure these breeds can flourish, without the fear of Collie Eye Anomaly.

Recognizing Symptoms in Dogs

Understanding Collie Eye Anomaly in dogs is key. But, spotting the signs is equally important. Dog genes and breeding matter in this condition. Good eye care is also vital.

Signs can include the dog’s eyes looking smaller. Or they may look cloudy. Sadly, it’s often hard to spot until the dog goes blind. That’s why eye checks are vital for young dogs at risk.

Spotting signs early can help your pet’s life quality. So, knowing these signs is crucial for your pet’s health.

Causes: Genetics and Breed Predispositions

To understand why Collie Eye Anomaly happens, we have to look at dog’s genes and breed. This issue is passed down in the genes. Some dog breeds, like Collies, are more likely to get it. That’s because the bad gene is common in these breeds.

The type of dog can influence if this problem happens. So, if you’re thinking of getting a dog, think about genetic testing. It could help spot dogs with this issue before they have puppies. This may lower the number of dogs with this problem.

Picking the right breed and testing genes can help control this issue in dogs prone to it.

The Role of Chromosome 37

Chromosome 37 is key in understanding Collie Eye Anomaly. This eye problem in dogs is tied to a flawed gene on this chromosome. Breeding plays a big part in this. When dogs with this flawed gene have puppies, the puppies may also have it. This is how the eye problem can spread.

The role of chromosome 37 is important. Knowing about it helps us handle this issue better. It underlines the need for careful breeding and testing.

Treatment Options for Affected Dogs

Dealing with Collie Eye Anomaly requires vet care and changes at home. One key part is helping dogs with sight loss. This focuses on keeping their life quality high. New vet methods have improved the handling of this issue. But, there is no cure yet.

Regular eye checks can spot early signs. This makes timely help possible. In serious cases, surgery may be needed. Home changes include making a safe space for the dog to move around. Each case is different. But, these treatment steps can greatly help dogs with Collie Eye Anomaly.

This goes to show the strong bond between pets and their owners.

Living With a Visually Impaired Dog

Taking care of a dog that can’t see well needs kindness and patience. You need to know what your dog needs and find good ways to help them. Make your dog feel safe by talking to them often. Keep things in the same place so they don’t get lost or confused. Use sounds to talk to your dog. Train them to use their nose and touch.

Keep your dog healthy with exercise and good food. Your dog is not hurting because they can’t see. They just see the world in a different way. With time, love, and understanding, you can help your dog have a good life.

Prevention and Regular Check-ups

Because some dogs can inherit diseases like Collie Eye Anomaly, it’s important to take steps to keep them healthy. Regular vet visits are a must. These visits can help spot early signs of this eye problem. Quick action can then be taken.

Genetic testing is also a key part in keeping dogs safe, especially for certain breeds. This test can find dogs that carry the bad gene. This can stop it from being passed on to puppies.

As dog lovers, we need to do these things. They can help keep a dog’s sight safe. They can also ensure dogs live happy, healthy lives.


In short, Collie Eye Anomaly is a gene problem that mainly affects Border Collies and Australian Shepherds. This issue concerns pet owners and dog breeders significantly.

Regular eye check-ups are crucial to catching this problem early. It is also essential to understand the role of chromosome 37 and explore treatment options.

Collie Eye Anomaly can lead to poor sight or blindness, but not all dogs with this condition will lose their vision. While it cannot be reversed, we can enhance dogs’ quality of life by making adjustments to their living environment.
