Why is my dog's paw pad blackened or bruised?

Overview
A dog paw pad that looks blackened or bruised is often due to minor trauma, pressure, friction, or something irritating the paw. It can also be a sign of a cut, a trapped thorn or seed, or a skin problem between the toes. The colour change on its own doesn't tell you the cause, so it's best to check the paw carefully and monitor how your dog is moving.
Things To Check
1. Notice when you first saw the change and whether it appeared after a walk, play, grooming, or rough ground.
2. Look for swelling, heat, redness, scabs, cracks, bleeding, or any broken skin on the pad or between the toes.
3. Check whether your dog is licking, biting, favouring the paw, or seeming reluctant to walk on it.
4. Gently see if there is grit, a thorn, a grass seed, or another small object stuck in the paw.
5. Compare the affected pad with the others to see if the colour change is patchy, evenly dark, or looks like a bruise.
6. Check the nails and the skin around the paw for signs of injury, wear, or irritation.
7. Think about recent changes such as hot pavements, long walks, muddy ground, new surfaces, or a change in exercise.
Common Causes
The most common reasons are minor knocks, pressure, or friction from walking on hard or rough surfaces. A paw pad can also look darker after rubbing or a small bump, much like a bruise.
Another common cause is a small injury such as a cut, scrape, burn, or something trapped in the paw. These can be easy to miss at first, especially if the fur is thick or your dog doesn't like paw handling.
Less commonly, a darkened area can be linked to ongoing irritation, infection between the toes, a foreign body that has worked deeper into the tissue, or a change in the skin itself.
What To Do
Check the paw in good light and, if your dog allows it, rinse away dirt with lukewarm water. Dry the paw well afterwards, especially between the toes.
Keep exercise gentle for a day or two and avoid rough, hot, or abrasive ground if the pad looks sore. If there is a small surface wound, keep an eye on it and stop your dog from licking it as much as possible.
Watch for changes over the next 24 to 48 hours. If the area is getting darker, your dog is limping more, or the paw looks swollen or painful, it’s sensible to seek veterinary advice.
