Understanding Viral and Bacterial Infections in English Bulldogs A Realistic, Responsible Guide for Buyers

January 8, 2026

English Bulldogs, like all dogs, can be affected by common viral and bacterial infections. These infections are environmentally acquired, not genetic or congenital, and are not a reflection of breeder care or quality. At WB English Bulldogs, we believe it is essential for families to understand the risks, causes, and management of these infections.

1. What Are Viral and Bacterial Infections?

Viral infections are caused by viruses such as parvovirus, distemper, parainfluenza, or adenovirus.
Bacterial infections can include respiratory infections (like Bordetella), gastrointestinal infections, urinary tract infections, or skin infections.
These pathogens are common in all dogs and can be spread through contact with other dogs, contaminated surfaces, or environmental exposure.

2. How Puppies Are Exposed

Even healthy, vaccinated puppies can be exposed to infections after leaving the breeder’s care. Common exposure sources include:

Contact with other dogs or wildlife
Public spaces, sidewalks, or dog parks
Veterinary clinics, grooming facilities, or daycare centers
Contaminated objects such as bowls, toys, or bedding

Exposure in the new home or environment is completely beyond the breeder’s control.

3. Common Signs of Infection

Signs vary depending on the type of infection but may include:

Coughing, sneezing, or nasal discharge
Vomiting or diarrhea
Fever or lethargy
Skin irritation, redness, or sores
Loss of appetite or unusual behavior

Some infections can be mild and self-limiting, while others may require prompt veterinary care.

4. Vaccination and Preventive Care

Vaccines are available for many viral and bacterial pathogens but do not guarantee absolute immunity.
Maternal antibodies may partially protect puppies early in life but can also interfere with vaccine effectiveness.
Even fully vaccinated puppies may experience mild symptoms if exposed to high levels of pathogens or multiple infections simultaneously.

5. Why These Infections Are Not Covered Under Our Health Warranty

WB English Bulldogs’ one-year health warranty does not cover viral or bacterial infections because:

They are environmentally acquired, not congenital or hereditary.
Risk of exposure increases once puppies leave the breeder’s controlled environment.
Vaccination and preventive care reduce severity but cannot completely prevent infection.
Prompt veterinary care is the owner’s responsibility.

These infections are common in all breeds and are considered normal environmental risks, not breeder negligence.

6. Responsible Ownership and Care

Owners should:

Complete all recommended vaccinations and follow veterinary guidance
Maintain a clean living environment and good hygiene
Minimize exposure to unknown or unvaccinated dogs
Seek prompt veterinary attention for any signs of illness

With proper care, puppies are highly likely to remain healthy and recover fully if exposed.

7. Setting Proper Expectations

As professional English Bulldog breeders since 1998, WB English Bulldogs is committed to producing healthy puppies and educating families.

Viral and bacterial infections are common, environmentally acquired conditions, not a reflection of breeder practices. Understanding risks and practicing responsible care ensures the best outcome for every puppy.
