Canine distemper virus (CDV) is a highly contagious viral diseaseĀ that affects puppies and dogs of all breeds. While it is serious and sometimes fatal, it isĀ not genetic, not congenital, and not a reflection of breeder quality or care. Distemper isĀ acquired through environmental exposure, typically from contact with infected dogs or contaminated surfaces.
At WB English Bulldogs, we prioritize transparency and education so buyers understand potential risks and responsibilities associated with puppy ownership.
1. What Is Canine Distemper?
Canine distemper is caused by a virus in theĀ MorbillivirusĀ family. It attacks theĀ respiratory, gastrointestinal, and nervous systemsĀ of infected dogs. Puppies under six months are most susceptible, particularly if they haveĀ not completed their full vaccination series.
The virus spreads throughĀ respiratory droplets, bodily fluids, or contaminated objects, making it highly contagious.

2. How Puppies Are Exposed
Puppies can be exposed through:
-
Contact with infected dogs or wildlife
-
Shared environments such as kennels or veterinary clinics
-
Contaminated surfaces, water bowls, or equipment
-
Unvaccinated dogs or new pets in the household
Even with excellent breeder care, exposureĀ after leaving the breederās facilityĀ is a normal and unavoidable risk.
3. Common Signs of Distemper
Symptoms vary depending on the severity and organs affected, but may include:
-
Fever
-
Lethargy
-
Loss of appetite
-
Nasal or eye discharge
-
Coughing or labored breathing
-
Vomiting or diarrhea
-
Neurological signs in advanced cases, such as seizures or tremors
Early veterinary intervention is critical, as distemper can progress rapidly in unvaccinated puppies.

4. Vaccination Is Key, but Not Immediate Protection
-
Puppies rely onĀ maternal antibodiesĀ for early protection, which fade at different rates.
-
Vaccines reduce risk but doĀ not provide immediate or absolute immunity.
-
A puppy may appear healthy at placement but remain vulnerable to infection for a short period.
5. Distemper Is Environmental, Not Genetic
-
Canine distemper isĀ not inheritedĀ and isĀ not caused by poor breeding or care.
-
Even in the healthiest, most carefully managed litters, a puppy can be exposed and develop the virus after leaving the breeder.
-
Veterinary literature classifies distemper as anĀ environmental infectious disease, not a congenital condition.

6. Why Distemper Is Not Covered Under Our Health Warranty
WB English Bulldogsā one-year health warrantyĀ excludes environmental infectious diseasesĀ because:
-
Exposure can occurĀ after placement
-
Risk is influenced by environmental factors beyond the breederās control
-
Vaccination timing and maternal antibodies affect susceptibility
-
Distemper isĀ not congenital or hereditary
Owners are responsible for prompt veterinary care, vaccination completion, and environmental precautions.
7. Responsible Ownership and Prevention
We strongly encourage owners to:
-
Complete the full distemper vaccination series as recommended by their veterinarian
-
Avoid contact with unvaccinated or unknown dogs
-
Maintain clean environments and hygiene practices
-
Seek immediate veterinary attention if symptoms develop
With proper vaccination and care, puppies are very likely to remain healthy.
8. Setting Proper Expectations
As professional English Bulldog breeders since 1998, WB English Bulldogs is committed to producing healthy puppies and educating families about real-world risks.
Canine distemper is aĀ well-documented, contagious viral disease, not a reflection of breeder quality. Education, vaccination, and responsible care are the best ways to protect puppies after placement.
