Dog paw pads are living tissue: they are irrigated by blood vessels, contain nerve endings and bear the animal's weight at every step. In winter they become the most exposed part of the body to external attacks: the cold, the salt used to melt ice, wet mud and the chemicals on the road surface. Knowing the risks and how to act can prevent problems ranging from mild irritation to infections or poisoning.
Why paws are particularly vulnerable in winter
Unlike the rest of the body, paw pads are in direct contact with the ground at all times. There is no hair layer to protect them from the cold, nor distance to separate them from road contaminants. The fatty tissue of the pads provides some natural insulation, but when temperatures drop very low or exposure is prolonged, that mechanism is insufficient. Moreover, the spaces between the toes accumulate snow, salt and mud — moist areas that favour the growth of fungi and bacteria.
Ice-melt salt: irritation and poisoning risk
Salt and chemical de-icers spread on pavements, roads and car parks are one of the greatest winter risks for dogs. Walking on treated surfaces, salt crystals stick to the paw pads and the spaces between the toes, causing irritation, redness and, with prolonged exposure, cracks or open wounds. The problem worsens when the dog licks its paws on arriving home: it may ingest the chemical substances, which can cause vomiting, diarrhoea or, in high doses, more serious harm. Washing the paws with lukewarm water as soon as you return from the walk is the most effective measure to neutralise this risk.
Mud, moisture and the risk of fungal infection
Wet mud and snow accumulated in the spaces between the toes create a warm, moist environment ideal for the growth of fungi and bacteria. The most common symptoms are compulsive paw licking, interdigital redness, bad odour and, in more advanced stages, nodules or crusts. Thoroughly cleaning and drying the paws after every walk, paying special attention to the spaces between the toes, is the best prevention.
Extreme cold and damage to the pads
In extremely cold conditions, especially at temperatures below 0 °C and on icy surfaces, the pads may suffer injuries similar to frostbite. These manifest as whitening, stiffness or, later, blisters. Northern breeds with more robust pads tolerate extreme cold better. Mediterranean or indoor breeds with thinner pads are more vulnerable. If the walk is long or temperatures are very low, protective booties are a valid option, provided the dog is used to wearing them.
How to clean the paws after every walk
Post-walk cleaning in winter should be a daily ritual. The process is simple:
- Use lukewarm water (never hot) to rinse the pads and the spaces between the toes thoroughly. Specific wet wipes are also useful for a quick clean away from home.
- Dry completely with an absorbent towel, leaving no residual moisture.
- Check for wounds, cracks, redness or foreign bodies (salt, ice crystals).
- If the dog resists, do it gradually with positive reinforcement until it accepts it without stress.
How to protect and moisturise the pads
Dry or cracked pads need moisturising. There are specific paw balms, such as the first aid cream, that create a protective barrier against salt and cold while nourishing the tissue. Applied before the walk they form a protective layer; applied after, on dry and clean paws, they aid recovery. A balanced diet rich in essential fatty acids also promotes the health of the skin and pads from the inside. Supplements with omega-3 can be extra help if you notice the condition of the pads worsens during the cold months.
