Hydrocephalus in Dogs: Causes, Symptoms, and Treatment Understanding and Managing Hydrocephalus in Dogs

Hydrocephalus in Dogs: Causes, Symptoms, and Treatment

Hydrocephalus is a major challenge for dogs and their owners, necessitating a thorough understanding of the condition. This article will look at the causes, symptoms, and treatment options for hydrocephalus in dogs, shedding light on the condition and its impact on our canine companions.

The abnormal buildup of cerebrospinal fluid (CSF) in the brain's ventricles is known as hydrocephalus. It can happen to dogs, just like it can happen to humans and it can have a serious impact on how well they live. Hydrocephalus, whether congenital or acquired later in life, demands correct understanding and management for the well-being of our canine companions.

This article will look at the origins, symptoms, and treatment options for hydrocephalus in dogs, shining light on the illness and its influence on our furry friends.


The causes of Hydrocephalus in dogs could be congenital or acquired.

  • Congenital: Congenital hydrocephalus in dogs makes up the majority of the instances of canine hydro, which means they were present at birth. It can be caused by hereditary causes or developmental anomalies in the puppy's early stages of development.

  • Acquired: Head injuries, illnesses, tumors, or other conditions that restrict the flow or absorption of CSF inside the brain can often cause hydrocephalus to appear later in life.

Hydrocephalus in Dogs Symptoms

The symptoms of hydrocephalus in dogs vary depending on the gravity of the disease. Known symptoms for a dog with hydrocephalus include:

  • Head Enlargement: One of the key indications of congenital hydrocephalus in pups is an excessively big or dome-shaped head in comparison to its body size. This is caused to a buildup of cerebrospinal fluid.

  • Behavioral Changes: Dogs suffering from hydrocephalus may display strange behavior. They may become more anxious, restless, or irritated. They may exhibit temperamental changes or unusual hostility.

  • Seizures: A major symptom of hydrocephalus is seizures. Generalized seizures in dogs can include convulsions, loss of consciousness, muscular twitching, or rhythmic movements. The frequency and intensity of seizures might vary.

  • Motor Difficulties: Hydrocephalus can impair coordination and movement. Affected dogs may struggle to move, seem unstable on their feet, stumble or fall frequently, or lack coordination.

  • Visual Disturbances: Dogs with hydrocephalus frequently experience vision issues. They may have blindness, partial vision loss, or other visual abnormalities. This can show as things colliding, apparent confusion, or dilated pupils.

  • Head Pressing: Dogs with hydrocephalus may display head pressing, a behavior in which they repeatedly press their heads against walls, furniture, or other things. This habit is an effort to relieve pain or pressure in the brain.

  • Urination or Defecation Changes: In certain circumstances, hydrocephalus can impair bladder and bowel control. Dogs may struggle to regulate urine or feces, resulting in accidents inside or an inability to empty their bladder or intestines adequately.

Diagnosis for Hydrocephalus Dogs

The vet usually employs the following steps and tests to diagnose hydrocephalus in dogs:

Hydrocephalus in Dogs Treatment

The goal of treatment for hydrocephalus in dogs is to minimize CSF buildup and relieve symptoms. The strategy might include the following:

  • Medications: Diuretics or corticosteroids may be administered to decrease fluid production or increase absorption.

  • Surgical intervention: In some circumstances, a ventriculoperitoneal shunt implantation surgery may be performed. This entails inserting a conduit (shunt) to drain excess fluid from the ventricles of the brain to another portion of the body where it may be absorbed.

  • Supportive care: Supportive treatment includes treating symptoms like seizures with anticonvulsant drugs and providing a safe environment for the dog.

Preventive Tips

Unfortunately, there are no particular techniques for preventing congenital hydrocephalus. However, general activities you may take to enhance overall health and lessen the likelihood of specific illnesses in dogs include:

  • Responsible breeding: If you are a breeder or intend to purchase a dog from a breeder, it is critical that you select responsible breeders that value the health of their breeding stock. They should undergo proper health exams, including genetic testing, to limit the chance of passing on inherited diseases like hydrocephalus.

  • Genetic testing: For breeds known to be predisposed to hydrocephalus, genetic testing can aid in identifying carriers of the condition's related genes. By selecting mating partners that are devoid of these alleles, the risk of having kids with hydrocephalus is reduced.

  • Prenatal veterinarian care: This includes frequent veterinarian check-ups, giving the mother a healthy diet, adequate activity, and frequent immunizations to reduce the risk of illnesses that might contribute to hydrocephalus in the puppies.

  • Avoiding head trauma: To reduce the danger of head injuries in your dog, ensure a safe environment, and use suitable automobile seats or harnesses particularly when outdoors or traveling with your furry friend.

  • Safety Measures: Head trauma that can result in hydrocephalus may not always be prevented but you can maintain a safe environment, employ suitable automobile seats or harnesses, and supervise activities that may include rough play or potential fall to reduce your dog's risk of head injury.

It's crucial to note that congenital hydrocephalus can occur even if precautions are taken. If you believe your dog's puppies have hydrocephalus or another health concern, visit a veterinarian immediately for accurate diagnosis and treatment. Early intervention and adequate therapy can improve the prognosis of afflicted pups dramatically.
