Salt and other de-icing chemicals can be harmful to your pet. Before taking your dog outside, massage petroleum jelly or a paw-protectant solution on their paw pads to help prevent redness and irritation, recommends the ASPCA. Winter boots made for pets may also be a good idea to help protect their paws.

When bringing your pet back inside, use a towel to wipe down their paws and belly to help remove any chemical residue from their body, says the Humane Society of the United States. This can help prevent your pet from ingesting harmful chemicals if they lick their paws.
