What should I check if my dog's paw pads are blistered after winter road salt?

Overview
If your dog’s paw pads look blistered after winter road salt, the first thing to do is check how sore they seem, whether the skin is only red and irritated or whether it’s actually broken, and whether the problem improves once the paws are cleaned and kept away from salt. Road salt can cause simple irritation, but blistering can also happen if the skin has been rubbed, cracked or already sensitised by cold, wet weather.
Things To Check
1. Check whether the problem started straight after a walk on salted roads, paths or car parks.
2. Look closely at each pad for redness, swelling, blisters, splits, bleeding, scabs or discharge.
3. Check the skin between the toes as well, because salt can cling there and irritate hidden areas.
4. See whether your dog is licking, chewing, limping or lifting the paw more than usual.
5. Feel for obvious heat or tenderness compared with the other paws.
6. Check whether only one paw is affected, since that can sometimes point to a local scrape, cut or something trapped in the foot rather than salt alone.
7. Think about any recent grooming, very long walks or icy ground, as these can add to paw pad stress.
Common Causes
The most common cause is simple irritation from road salt, especially if your dog has walked through a lot of slush, grit or de-icing products. Cold weather can also make pads drier and more prone to cracking or surface damage.
Sometimes the pads are not blistered in the true sense, but look raised because of rubbing, cracking or minor chemical irritation. Less commonly, a cut, trapped grit, or an early skin infection can make the area look sore and blistered too.
What To Do
Rinse the paws with lukewarm water after walks to remove salt and grit, then dry them gently, especially between the toes. Keep walks shorter on heavily salted routes for a few days if you can, and try to use cleaner paths or grass instead.
Check the paws again later the same day and over the next couple of days so you can see whether the skin is settling or getting worse. Try to stop licking where possible, because that can make irritation last longer.
If the pads are only mildly irritated, calm cleaning and avoiding further salt exposure is often enough to help the area settle. If the skin is open or your dog seems painful, keep handling gentle and avoid rough surfaces until it looks more comfortable.
When To Contact A Vet
Contact your vet if the blisters are open, bleeding or oozing, if your dog is lame or clearly uncomfortable, or if the paw looks increasingly swollen, hot or red. It’s also sensible to get advice if the problem doesn’t improve within a day or two of keeping the paws clean and away from salt.
