Bordetella Vaccine and Canine Sleepiness

Bordetella Vaccine & Sleepiness

Yes, the Bordetella vaccine can make dogs sleepy. This is a common and typically mild side effect that many pet owners observe (Source 2). The sleepiness indicates that the dog's immune system is actively responding to the vaccine, working to build protection against kennel cough (Source 2).

Why Dogs Get Sleepy After Vaccination

Immune System Response

When a dog receives the Bordetella vaccine, its immune system is stimulated to produce antibodies. This process requires energy, similar to how humans might feel tired after fighting off an illness. The body is actively working to build immunity, which can temporarily deplete energy levels and lead to lethargy (Source 2, Source 5).

Mild Inflammation

The immune response triggered by vaccination can also cause mild, temporary inflammation within the body. This inflammatory process, while a normal part of building immunity, can contribute to a general feeling of malaise and tiredness in dogs (Source 5).

Common Side Effects (Beyond Sleepiness)

While sleepiness is a frequent reaction, dogs can experience other mild side effects after receiving the Bordetella vaccine. These are generally temporary and resolve on their own.

• Mild lethargy/reduced activity: Dogs may be less energetic or playful than usual for a day or two (Source 4).
• Sneezing, mild cough: This is particularly common with the intranasal (nose drop) form of the vaccine, as it mimics a natural infection to stimulate immunity (Source 4).
• Low-grade fever: A slight increase in body temperature can occur as the immune system responds (Source 5).
• Temporary loss of appetite: Some dogs might show less interest in food for a short period (Source 5).
• Slight swelling or tenderness at the injection site: This applies to the injectable form of the vaccine and is usually minor (Source 5).
• Gastrointestinal upset: Less commonly, dogs might experience mild vomiting or diarrhea (Source 1).

Managing Post-Vaccination Sleepiness & Other Mild Side Effects

Managing your dog's comfort after vaccination can help them recover smoothly. Most mild side effects resolve within 24 to 48 hours (Source 4, Source 5).

• Provide a quiet, comfortable resting area: Ensure your dog has a peaceful spot to rest without disturbances.
• Ensure access to fresh water: Hydration is important, especially if your dog has a mild fever or reduced appetite.
• Offer small, easily digestible meals if appetite is reduced: Bland options like boiled chicken and rice can be helpful.
• Avoid strenuous exercise or overly exciting activities for 24-48 hours: Allow your dog to conserve energy for recovery.
• Monitor behavior closely: Observe for any changes that might indicate a more serious reaction.

When to See a Vet

While most post-vaccination reactions are mild, some symptoms warrant immediate veterinary attention. It's crucial to know when to seek professional help (Source 4, Source 5).

• Symptoms persist beyond 48 hours: If lethargy, coughing, or other mild side effects do not improve within two days.
• Severe lethargy or unresponsiveness: If your dog is extremely weak, difficult to rouse, or unresponsive.
• Persistent vomiting or diarrhea: If gastrointestinal upset is severe, frequent, or lasts for more than a day.
• Difficulty breathing or severe coughing: These can be signs of a more serious respiratory reaction or an allergic response.
• Facial swelling, hives, or severe itching: These are classic signs of an allergic reaction and require immediate veterinary care (Source 4).
• Pain or severe swelling at the injection site: While mild tenderness is normal, significant pain or swelling should be checked.
• Any sudden, alarming behavioral changes: Trust your instincts if your dog's behavior seems unusually concerning.

Bordetella Vaccine Forms

The Bordetella vaccine is available in several forms, each with its own administration method and potential side effect profile (Source 1).

• Injectable: This form is given as a shot, typically under the skin. It often causes fewer respiratory symptoms like sneezing or coughing but can lead to localized reactions at the injection site, such as mild swelling or tenderness (Source 4).
• Intranasal: Administered as drops into the dog's nose, this vaccine mimics a natural infection to stimulate immunity. Consequently, it can cause more sneezing, nasal discharge, or a mild cough as the dog's immune system responds to the localized exposure (Source 4).
• Oral: This vaccine is given by mouth. It is generally well-tolerated and may cause mild gastrointestinal upset in some dogs, though this is less common (Source 1).
