Des Moines, IA – As the first winter snow moves across Iowa and temperatures fall into the 20s, veterinarians are reminding pet owners that cold weather isn’t the only hazard this season. The road salt and chemical de-icers used to keep streets and sidewalks safe can burn paw pads, irritate skin, and cause toxic reactions if pets lick or ingest them.
Common de-icing products used across the state contain sodium chloride, calcium chloride, or magnesium chloride, chemicals that are effective at melting snow but harsh on pets’ paws. Even a short walk on salted surfaces can lead to dryness, cracking, or burns. When dogs lick their paws afterward, they may swallow these substances, leading to vomiting, diarrhea, excessive thirst, or lethargy. In severe cases, veterinarians warn that salt poisoning can result in seizures or kidney damage.
Veterinarians note that Iowa’s extensive road-salt programs—especially along major highways and in city neighborhoods—make repeated exposure likely during the winter months. Some commercial ice melts also contain industrial additives or heavy metals, adding to the risk of toxicity over time.
To protect pets, experts recommend rinsing their paws with warm water after each walk and drying them thoroughly. Applying a paw balm or wax before going outdoors helps prevent irritation, and trimming fur between toes keeps salt from clumping or freezing. Booties offer an extra layer of protection for dogs that tolerate them. Homeowners are encouraged to switch to chloride-free, pet-safe ice melts around driveways and walkways.
With snow showers and freezing drizzle expected across the state this weekend, veterinarians urge owners to stay alert for limping, licking, or reluctance to walk—early signs of irritation or burns from salt exposure.
As winter settles across Iowa, experts emphasize that the biggest threat to pets isn’t just the cold—it’s the chemicals spread to fight it.
