Can Flood Water Damage Make Pets and Animals Sick?
Last updated October 26, 2026
The short answer
What Is in Flood Water
Flood water is rarely clean. It can carry sewage, agricultural runoff, fuel, and other harmful substances. When pets wade through or drink it, they can swallow bacteria like E. Coli or parasites such as giardia. Even contact with skin can lead to rashes or infections, especially if your pet has a cut or sore.
After the water recedes, the same contaminants stay behind in mud and on surfaces. Pets that walk through the area can pick up these germs on their paws and then groom themselves. That is why it is important to rinse your pet's paws and body with clean water after any contact with flood-affected zones.
- Keep pets out of standing water and mud
- Rinse paws and fur with clean water after outdoor time
- Do not let pets drink from puddles or flooded areas
- Dry your pet thoroughly to prevent skin irritation
- Check for cuts or sores that may have been exposed
Health Risks for Pets
Common health problems from flood water include vomiting, diarrhea, and fever. Leptospirosis is a bacterial infection that pets can get from contaminated water, and it can also affect humans. Mold that grows after water damage can cause respiratory issues in pets, just as it can in people.
Signs of illness in pets can be subtle. Watch for changes in appetite, energy level, or bathroom habits. If your pet seems lethargic, has trouble breathing, or shows any unusual symptoms after being near flood water, contact a veterinarian promptly. Early care can make a big difference.
How to Protect Your Pets
The right way to protect your pets is to keep them away from flooded areas entirely. During cleanup, confine pets to a dry, clean part of the home. If you must take them outside, use a leash and keep them on paved surfaces that have not been submerged.
After the flood, check your yard for debris, sharp objects, or standing water before letting pets out. Remove any dead animals or waste that may have washed in. Clean and disinfect any pet bowls, toys, or bedding that came into contact with flood water.
- Use a leash to control where your pet walks
- Clean pet bowls and toys with soap and disinfectant
- Wash bedding and crates that got wet
- Keep pets indoors until affected areas are dry
- Store pet food in sealed containers to avoid contamination
When to See a Veterinarian
If your pet shows any signs of illness after flood exposure, see a veterinarian. This is not a time to wait and see. Symptoms like vomiting, diarrhea, or unusual tiredness can indicate a serious infection. A vet can run tests and provide treatment.
Even if your pet seems fine, it is wise to mention the flood exposure during any routine visit. Some infections have a delayed onset. Your veterinarian can advise on vaccinations or preventive care that might be appropriate for your area.
Cleaning Up After the Flood
Proper cleanup is key to keeping your pets safe after a flood. Remove any wet carpet, drywall, or insulation that can harbor mold and bacteria. Dry out the home as quickly as possible, since mold can start growing within days. Use fans and dehumidifiers to speed up the process.
If the flood affected a large part of your home, consider hiring local water damage pros for the cleanup. They have the equipment to dry out structures thoroughly and can help dispose of contaminated materials safely. This reduces the risk of illness for both you and your pets.
If you live in St. Petersburg, remember that the humid climate can make drying out slower, so act quickly. The pros can also help with water damage inspection and documentation, which may be useful for your insurance claim. Policies vary, and your insurer decides what is covered.

Can pets get sick from licking flood water off their fur?
Yes, licking contaminated fur can expose pets to bacteria and parasites. Even small amounts can cause stomach upset or more serious infections. Always rinse and dry your pet after any contact with flood water, and see a vet if you notice symptoms.
How long after flood exposure can pets show symptoms?
Symptoms can appear within hours or take several days, depending on the infection. For example, leptospirosis may take a few days to show. Watch your pet closely for a week and contact a veterinarian if anything seems off.
Should I keep my pet inside during flood cleanup?
Yes, keep pets in a clean, dry room away from the cleanup area. Flood debris and cleaning chemicals can be harmful. This also reduces their stress and keeps them from getting in the way of the work.
