Black mould toxicity in dogs: causes, symptoms & treatment
Mould is often associated with spoilt food, but black mould that grows in damp homes can be invisible danger impacting your dog’s health. This persistent mould releases harmful spores that can cause respiratory issues, allergies, and much more if your dog breathes them in regularly. Understanding black mould toxicity is essential for every dog owner to safeguard their pet’s wellbeing and home environment.
What is black mould and how does it form?
Black mould usually refers to Stachybotrys chartarum, a common mould species that thrives in damp or water-damaged buildings. It appears as a black or dark green slimy patch, often found in corners of walls, ceilings, or floors where moisture accumulates. Leaking roofs, poor ventilation, and internal water damage create perfect conditions for this mould to grow.
Homes with prolonged damp problems can develop large areas covered by black mould, making it a significant health hazard not only to people but also to pets like dogs. The mould produces mycotoxins—poisonous substances that can cause various health disorders when inhaled or contacted.
Recognising black mould toxicity symptoms in dogs
Most dogs with black mould exposure show symptoms gradually, as the toxicity develops over time from breathing in spores in their home environment. Awareness of early signs allows prompt veterinary intervention to improve outcomes.
- Persistent coughing or wheezing: Indicative of respiratory irritation caused by spores.
- Noisy or laboured breathing: Dogs may struggle with oxygen intake, especially during exercise.
- Red, itchy eyes or skin irritation: Allergic reactions to mould spores affecting eyes and skin.
- Lethargy and reduced appetite: Dogs may appear generally unwell and lose interest in food.
- Declining exercise tolerance: Difficulty keeping up with walks or playtime.
If unchecked, prolonged exposure to black mould can severely damage lung tissue, weaken immune defences, and even cause internal haemorrhages in lungs, which can be fatal.
What to do if you suspect black mould poisoning in your dog
If your dog shows the symptoms described and you know or suspect black mould is present in your home, inform your vet immediately. Bringing a sample of the suspected mould can assist diagnosis.
The vet will typically perform blood tests to check for mycotoxin exposure and assess respiratory health. Treatment primarily focuses on removing your dog from the contaminated environment to halt further exposure and supporting their respiratory system as it recovers.
Medications might include anti-inflammatory drugs, coughing suppressants, and treatments for secondary infections if needed. Early intervention greatly improves the chances of recovery.
How to safely eradicate black mould in your home
Eliminating black mould is essential for the health of all household members, including your dog. Key steps include:
- Identify and fix the source of moisture: Repair leaking roofs, windows, pipes, and improve ventilation to reduce humidity.
- Remove existing mould: Use suitable cleaning products such as borax or specialised mould removers. Always wear protective gloves, clothing, and a mask.
- Keep pets and family away during cleaning: Disturbing mould releases spores into the air, so exclude dogs from affected rooms during remediation.
- Maintain good airflow and control humidity: Use dehumidifiers and air purifiers to keep spores at bay.
- Regularly inspect for re-growth: Frequent checks prevent mould from returning unnoticed.
Professional mould remediation services are recommended when mould covers large areas or penetrates air systems.
Preventing black mould risks for your dog
Prevention revolves around keeping your home dry and well-ventilated, especially in damp climates or seasons. Regular home maintenance to repair leaks and moisture build-up is crucial. Ensure your dog’s living areas and bedding stay dry and clean. Using air purifiers with HEPA filters in dog sleeping areas can help reduce airborne spores.
By proactively managing your home’s environment, you protect your dog from the slow but serious health consequences of black mould exposure.
