Introduction

Canine herpesvirus (CHV) is a devastating pathogen that can turn a joyful occasion into a heart-wrenching tragedy for pet parents and breeders alike. As a pet science blog author who has witnessed the impact of CHV firsthand, I feel compelled to share my insights and knowledge on this critical topic. In this article, we will explore the transmission, symptoms, diagnosis, and prevention strategies for CHV, aiming to equip pet parents with the necessary information to safeguard their furry family members.

Transmission

CHV is a stealthy and relentless viral disease that primarily targets puppies aged one to three weeks. The virus resides in the reproductive and respiratory tracts of both male and female dogs, making it a sexually transmitted infection. Adult dogs can carry the virus for years without showing any symptoms, a phenomenon known as “asymptomatic carriers.” This makes the transmission of CHV particularly challenging to detect and manage.

Puppies can contract CHV in several ways. The virus can cross the placenta and infect the puppies while they are still in the womb. Alternatively, they may be exposed to the virus through vaginal secretions during birth. The virus can also become airborne from the mother’s nasal secretions, allowing the puppies to inhale it after birth. Puppies can easily spread the virus among themselves, and it can also be transmitted through ingestion of infected materials.

Symptoms

The incubation period for CHV is approximately one week, which explains why puppies aged one to three weeks are at the highest risk. Infected puppies may exhibit a range of symptoms, including:

• Depression and cessation of nursing
• Soft, yellow-green feces
• Enlarged liver and painful abdomen
• Liver damage and impaired liver function
• Respiratory signs and nasal discharge
• Rash on the abdomen
• Hemorrhages, such as nosebleeds and bruises on mucous membranes or skin
• Neurological signs, such as blindness and staggering

Puppies typically succumb to the disease within 24-48 hours of showing symptoms. However, not all puppies exposed to CHV will become ill. Some may show no signs or only mild congestion and recover within a few days. Puppies exposed after six weeks of age have a better chance of recovery and may develop into carrier adults.

Diagnosis

CHV is a leading cause of death in newborn puppies, and its rapid spread through a litter makes it highly contagious. Unfortunately, many cases of CHV are misdiagnosed as parvovirus or coronavirus. A definitive diagnosis of CHV can be made through autopsies of deceased puppies by a veterinary pathologist, who will identify characteristic herpes lesions in the affected organs.

Treatment and Prevention

Currently, there is no specific treatment for CHV, and all efforts are focused on supportive care. Older puppies may be force-fed and treated with anti-diarrheal medication, but the survival rate for puppies under three weeks old remains poor. The best preventive practice is to maintain a warm environment for the puppies using whelping boxes, heat lamps, or other heat sources.

Conclusion

In conclusion, CHV is a formidable foe that can strike suddenly and without warning, causing the rapid decline and death of puppies, sometimes even an entire litter. It is crucial for pet parents and breeders to be vigilant and proactive in their prevention efforts. By understanding the transmission, symptoms, and prevention strategies for CHV, we can work together to protect our beloved puppies and give them the best chance at a healthy, happy life.

Remember, the mother dog may be a carrier, and future litters may be at risk unless she develops natural immunity. Until a vaccination is developed, it is our responsibility to provide the best possible care and environment for our puppies to combat this deadly virus.

Author’s Note

As a pet parent who has experienced the heartache of losing a puppy to CHV, I understand the pain and frustration that comes with this devastating disease. It is my hope that by sharing my knowledge and experiences, I can help others navigate this challenging situation and make informed decisions to protect their furry family members.
