Why does my dog tear with blood? - in detail

There are several reasons why your dog might be tearing with blood, and it's important to understand the underlying causes to provide appropriate care.

  1. Corneal Abrasion or Scratch: The most common cause of bloody tears in dogs is a corneal abrasion or scratch. This can occur when something irritates the eye, such as a foreign object, debris, or even the dog's own paw. The cornea has a rich blood supply, so any injury to it can lead to bleeding. Symptoms may include squinting, pawing at the eye, and excessive tearing.

  2. Eye Infection: Bacterial or viral infections can also cause bloody tears. These infections can be quite painful and may lead to inflammation of the eye (conjunctivitis) or other structures within the eye. If left untreated, infections can cause serious damage to the eye.

  3. Glaucoma: Glaucoma is a condition that occurs when there is increased pressure inside the eye. This can be very painful and may lead to bleeding from the eye as well as other symptoms such as dilated pupils, cloudy cornea, and loss of vision. Glaucoma is considered an emergency and requires immediate veterinary attention.

  4. Trauma: Trauma to the eye or surrounding structures can also cause bloody tears. This could be due to a direct blow to the eye, such as from another dog during play, or from other types of trauma like being hit by a car.

  5. Bleeding Disorders: In some cases, bloody tears may indicate an underlying bleeding disorder in your dog. These disorders can affect the body's ability to clot blood properly and may require further diagnostic testing and treatment.

  6. Tumors or Growths: Less commonly, tumors or growths within the eye or on the surrounding tissue can cause bloody tears. These growths can be benign or malignant and typically require surgical removal.

If your dog is tearing with blood, it's crucial to seek veterinary care promptly. Your vet will perform a thorough examination of the eye and may recommend various tests depending on the suspected cause. Treatment options may include topical or oral medications, surgery, or other interventions based on the underlying issue. Prompt diagnosis and treatment are essential for preserving your dog's vision and overall health.
