For most pet dogs, the overall risk of contracting brucellosis is low, but it becomes high in certain situations — especially around breeding, imported dogs, or contact with livestock or birthing materials.
📌 When the risk is higher
Each item begins with a Guided Link so you can explore more if you want:
- Breeding environments — Mating, pregnancy, miscarriages, and reproductive fluids create the highest transmission risk.
- Imported dogs — Dogs from regions where brucellosis is common may carry the infection silently.
- Farm or hunting dogs — Contact with livestock birth materials or raw meat from infected animals increases risk.
- Exposure to birthing fluids — The most infectious material; even brief contact can transmit the bacteria.
🏠 For typical household pets
For a neutered, non‑breeding dog living in a normal home environment (like yours in Tokyo), the risk is very low. Most infections occur only when dogs:
- mate with infected dogs
- lick or sniff birthing fluids
- come from high‑risk countries
- live around livestock
🧼 How to keep risk low
- Neuter/spay your dog (reduces reproductive spread).
- Avoid contact with birthing materials from any dog.
- Be cautious with imported dogs — ask for testing.
- Practice normal hygiene (washing hands after handling urine or feces).
📊 Quick risk table
| Situation | Risk Level | Why |
|---|---|---|
| Typical pet dog in urban home | Low | No exposure to reproductive fluids or livestock |
| Breeding dogs | High | Direct contact with infected reproductive tissues |
| Imported dogs from high‑risk regions | Medium–High | Higher prevalence of B. canis |
| Farm/hunting dogs | Medium–High | Contact with livestock birth materials or raw meat |
| Dogs exposed to infected birthing fluids | Very High | Most infectious route |
