Yes, canine distemper virus (CDV) severely affects the brain and central nervous system. It causes inflammation of the brain (encephalomyelitis), leading to symptoms like seizures, "chewing-gum" fits, tremors, incoordination, and paralysis. These neurological signs often appear after initial respiratory or gastrointestinal issues, sometimes appearing weeks or years after recovery.

What does distemper do to the brain?

Canine distemper virus (CDV) invades the nervous system and replicates in neurons and glial cell of the white matter during a period of severe viral induced immunosuppression. Demyelination occurs in infected white matter areas in the absence of inflammation.

Can distemper cause neurological problems in dogs?

Some dogs that recover from CDV may have residual muscular twitches or seizures. Others may develop neurologic signs in the weeks following recovery or years later, in a syndrome called “old dog distemper.”

Does distemper have long-term effects?

Although dogs that survive will have lifelong immunity to canine distemper virus, they usually have permanent, irreparable nervous system damage.

What are signs of brain damage in dogs?

• Symptoms of brain damage depend on the area of the brain affected.
• Blindness, abnormal pupil responses, balance problems, weakness of limbs, pain, seizures, stiff gait, head tilt, salivation, incontinence.........
• Symptoms will depend on the cause of the damage, and the area(s) damaged.

The 5 minute rundown: Canine Distemper

Can a dog recover from brain damage?

For a young dog with a minor primary brain injury, and secondary injury limited to fluid build-up in the brain, the long-term outlook is favorable.

What are the first signs of neurological issues in dogs?

The first signs of neurological issues in dogs often involve balance and coordination problems (wobbly walking, head tilting, circling), behavior changes (confusion, aggression, excessive vocalization), weakness (dragging paws, limb weakness), abnormal eye movements, and seizures or tremors, with subtle changes like pain or stumbling being crucial early indicators needing immediate vet attention.

What is the life expectancy of a dog with distemper?

A dog's survival with distemper varies greatly; many die, especially puppies, but survivors can live for years, often with permanent neurological issues like seizures or muscle twitches, while others may succumb to complications within weeks to months. The disease progresses rapidly, potentially causing death within 2-4 weeks without treatment, but prompt supportive care can improve outcomes, though long-term damage is common. 

What is the main cause of distemper in dogs?

Canine distemper is caused by a single-stranded RNA virus of the family Paramyxoviridae (the same family of viruses that causes measles and mumps in humans). The disease is highly contagious via inhalation.

What are the last stages of distemper?

In the extreme stages of the disease, the virus affects the other bodily systems, particularly the central nervous system (CNS); the dog may begin having seizures, fits and paralysis. Some strains of the virus can cause an abnormal enlargement or thickening (hyperkeratosis) of the foot pads and sometimes the nose .

Why is my dog acting confused and disoriented?

As dogs age and become seniors, they may experience cognitive decline, leading to behaviors like confusion, increased vocalization, or changes in sleep patterns. Conditions such as canine cognitive dysfunction (similar to Alzheimer's in humans) can cause disorientation and altered behavior.

What organs does distemper affect?

Canine distemper virus (CDV) is a very contagious virus that can cause severe disease in young dogs. Most commonly illness is seen in the respiratory tract (nose, wind-pipe/trachea, lungs/ pneumonia), the stomach and intestines (vomit, nausea and diarrhea), and the brain (seizures, tremors).

What are the neurological symptoms of distemper in dogs?

Dogs commonly exhibit systemic clinical signs (fever, lethargy, loss of appetite), respiratory signs (nasal discharge, pneumonia), and GI signs (diarrhea), variably followed by neurologic signs (muscle twitching, focal or generalized seizures), which may be delayed.

Can dogs go blind from distemper?

As distemper progresses, signs become more serious and extensive. Distemper can cause coughing, breathing difficulties, eye and nose discharges, vomiting and diarrhea, blindness, paralysis, and seizures. The seizures associated with distemper often have their own unique presentation, called chewing gum fits.

What can be mistaken for distemper in dogs?

Kennel cough can mimic the respiratory symptoms of canine distemper. Vomiting and diarrhea should be differentiated from canine parvovirus, corona virus infections, bacterial and internal parasite infections, etc.

Can distemper be misdiagnosed?

Distemper weakens the immune system, leaving affected dogs susceptible to secondary bacterial or fungal infections. These infections can obscure the underlying viral cause and lead to misdiagnosis.

Why did my vaccinated dog get distemper?

Although the disease is considered uncommon in countries with high vaccine coverage, occasional reports indicate that vaccinated dogs have shown signs of distemper following suspected field infection [4].

How long does it take for a dog to recover from distemper?

Recovery is usually dependent upon the strength of the dog's immune system and the strain of distemper they have contracted. It can take up to 2 months to fully recover.

Is distemper painful for dogs?

Yes. Distemper is very painful condition to the affected dogs. They suffer a lot from the inflammation in respiratory system, urinary system, nervous and muscles issues. The neurological damage can cause serious pain and discomfort in the animal.

What is the #1 cause of death in dogs?

The leading cause of death in dogs overall is cancer, especially in older dogs, affecting about one in four dogs, with specific breeds like Golden Retrievers, Boxers, and Bernese Mountain Dogs being highly susceptible. However, causes vary significantly by age and breed, with younger dogs often dying from trauma, while older dogs and larger breeds face higher risks from organ system failures like neurological, cardiovascular, and gastrointestinal issues.
 

How do dogs catch distemper?

Dogs catch distemper from other dogs or wild animals that are infected with it. They can catch it by having direct contact with the sick animal, or by standing near the animal when it is coughing. They can also catch it if they have contact with food bowls or other objects that were contaminated by infected animals.

What does brain damage in dogs look like?

There can be a variety of neurological symptoms from brain trauma that your pet may experience. Motor control issues such as circling in one direction, head tilting or displaying rapid or abnormal eye movement, or a difference in the size of the pupils may be present. Your pet may experience seizures.

What are the early warning signs of neurological deterioration?

Here are some early signs that may indicate a neurological issue:

• Frequent or severe headaches. ...
• Unexplained numbness or tingling. ...
• Muscle weakness or coordination problems. ...
• Sudden confusion or memory loss. ...
• Seizures or episodes of blacking out. ...
• Vision or speech changes. ...
• Tremors or involuntary movements.

What dog breeds are prone to neurological issues?

Small brachycephalic dog breeds, such as the pug and French bulldog, are prone to develop specific neurological conditions and spinal disorders in particular. One group of conditions heavily associated with the body conformation of these dogs are vertebral and spinal malformations.
