Canine distemper in dogs

Canine Distemper Symptoms and Treatment

Caring for a dog is one of life’s greatest joys. But alongside the companionship and happiness, we also bear the responsibility of protecting our furry friends from serious diseases. One such disease is Canine Distemper, a highly contagious and potentially life-threatening viral illness. Understanding its symptoms, knowing how to prevent it, and recognising treatment options are crucial to keeping your dog safe.

In this guide, we’ll explore the essential facts about Canine Distemper, helping you make informed decisions for your pet’s health and well-being.

‍

What is Canine Distemper?

Canine Distemper is a viral disease caused by the Canine Distemper Virus (CDV), which belongs to the Morbillivirus genus, related to the virus that causes measles in humans. It primarily affects dogs but can also infect other animals, such as ferrets, raccoons, and even large cats. Distemper attacks multiple body systems, including the respiratory, gastrointestinal, and nervous systems, often causing a range of symptoms and potentially serious complications.

How Serious is Canine Distemper?

Canine Distemper is considered one of the most serious and deadly diseases in dogs. It has a high mortality rate, especially in puppies and unvaccinated dogs. Though treatment can help manage symptoms, there is no cure, making prevention—especially vaccination—critical.

‍

Symptoms of Canine Distemper

Canine Distemper can cause a wide variety of symptoms, often progressing from mild to severe. The virus first targets the respiratory and digestive systems before moving into the nervous system.

Early Symptoms

In the initial stages, Canine Distemper often presents with symptoms similar to those of a cold or mild flu:

• Fever: A sudden rise in temperature, often noticed within 3–6 days of exposure.
• Watery to Pus-Like Discharge from Eyes and Nose: Often one of the first signs.
• Sneezing and Coughing: Respiratory symptoms that resemble a kennel cough.
• Loss of Appetite: Dogs may show reduced interest in food.
• Lethargy: A lack of energy and reluctance to play or move.

Advanced Symptoms

As the disease progresses, it affects the dog’s digestive and nervous systems:

• Vomiting and Diarrhoea: Common digestive symptoms that can lead to dehydration.
• Thickening of Footpads and Nose: Sometimes referred to as “hard pad disease,” this occurs in some cases and is a tell-tale sign of distemper.
• Nervous System Symptoms: In severe cases, the virus reaches the nervous system, causing:
  • Twitching or Muscle Spasms
  • Seizures
  • Paralysis
  • Incoordination (Ataxia)
  • Excessive Salivation or Chewing Movements: Dogs may appear as if they are chewing gum.

Complications of Canine Distemper

If left untreated, Canine Distemper can lead to serious complications:

• Pneumonia: Resulting from secondary bacterial infections.
• Neurological Damage: Lasting nervous system damage, including paralysis or behavioural changes.
• Blindness and Deafness: In advanced cases, distemper can cause permanent sensory loss.

If your dog exhibits any combination of these symptoms, especially if they are unvaccinated, it’s essential to contact your veterinarian immediately.

How is Canine Distemper Transmitted?

Canine Distemper is highly contagious, spreading through respiratory droplets and direct contact. Knowing how it spreads can help you protect your dog and prevent potential exposure.

Methods of Transmission

1. Airborne Transmission: Infected dogs release the virus through respiratory secretions (sneezing or coughing), which can spread to other dogs nearby.
2. Direct Contact: Physical contact with an infected animal or its body fluids can spread the virus.
3. Contaminated Surfaces: Shared bowls, toys, bedding, or even human hands can carry the virus, making hygiene essential in multi-dog environments.
4. Mother-to-Puppy Transmission: A mother infected with Canine Distemper may pass the virus to her puppies, making vaccination and prevention even more critical for breeding dogs.

The virus can survive for a short period outside a host but is easily killed by most disinfectants and cleaning agents.

Diagnosing Canine Distemper

Diagnosing Canine Distemper involves observing clinical symptoms and performing diagnostic tests. Since the disease shares symptoms with other conditions, it can sometimes be challenging to identify.

Diagnostic Steps

1. Physical Examination: A veterinarian will assess symptoms, particularly respiratory and neurological signs.
2. Blood Tests: Testing may show specific changes in blood cell counts that are indicative of infection.
3. PCR Testing: A Polymerase Chain Reaction (PCR) test, which detects the presence of the virus in blood, urine, or swabs from the eyes and nose, is commonly used to confirm the diagnosis.
4. X-rays: Chest X-rays may be taken to check for pneumonia or other respiratory complications.

Accurate diagnosis helps determine the best course of action for managing symptoms and providing supportive care.

‍

Treatment of Canine Distemper

Unfortunately, there is no cure for Canine Distemper. However, supportive care can alleviate symptoms, improve the dog’s quality of life, and help prevent secondary infections.

Supportive Treatments for Canine Distemper

1. Fluid Therapy: To prevent dehydration, especially in cases involving vomiting and diarrhoea.
2. Antibiotics: While they don’t kill the virus, antibiotics can treat secondary bacterial infections.
3. Anticonvulsants: To manage seizures in dogs showing neurological symptoms.
4. Anti-Inflammatory Medications: These can help reduce fever and ease discomfort.
5. Nutritional Support: Appetite stimulants or high-calorie foods may be necessary if the dog struggles to eat.

Home Care for Distemper

Caring for a dog with distemper at home requires patience and a calm, stable environment. Here’s how you can support your dog during recovery:

• Provide a Comfortable Rest Area: A quiet, warm, and comfortable space helps minimise stress.
• Ensure Hygiene: Regularly clean your dog’s bedding, toys, and bowls to reduce the risk of spreading the virus to other pets.
• Maintain Hydration: Encourage your dog to drink water and monitor for signs of dehydration.
• Observe for New Symptoms: Report any worsening symptoms to your vet promptly, especially neurological signs like twitching or seizures.

Preventing Canine Distemper

The most effective way to protect your dog from Canine Distemper is through vaccination. Vaccination is a safe, reliable, and widely available method that offers long-lasting immunity against the virus.

Vaccination for Distemper

1. Core Vaccine: The Canine Distemper vaccine is a core vaccine, meaning it’s recommended for all dogs regardless of lifestyle. It’s often administered as part of the DHPP (Distemper, Hepatitis, Parainfluenza, and Parvovirus) vaccine.
2. Puppy Vaccination Schedule: Puppies should receive their first dose at around 6–8 weeks of age, followed by additional doses until they are 16 weeks old.
3. Booster Shots: Adult dogs need regular booster shots, typically every 1–3 years, depending on the vaccine and veterinary recommendations.

Additional Prevention Tips

• Avoid Contact with Unvaccinated Dogs: Until your puppy is fully vaccinated, avoid areas with potentially unvaccinated dogs.
• Isolate Infected Dogs: If you suspect your dog has Canine Distemper, keep them isolated from other pets to prevent spread.
• Practice Good Hygiene: Wash your hands and clean shared spaces or items to prevent transmission.

The Prognosis for Dogs with Canine Distemper

The prognosis for Canine Distemper depends on the severity of symptoms, the age and health of the dog, and how early treatment begins. While some dogs recover fully, others may experience lasting effects, especially if neurological symptoms were severe.

Possible Long-Term Effects

For dogs that survive distemper, some may have lingering issues, including:

• Nervous System Damage: Permanent tremors or muscle twitches may remain.
• Sensory Loss: Some dogs may experience partial or total loss of vision or hearing.
• Behavioural Changes: In rare cases, dogs may exhibit behaviour changes due to brain inflammation.

While it’s possible for dogs to recover, recovery can take weeks to months, and close monitoring is essential.
