Why Do Dogs’ Paws Feel Hot?

Paws Sweat Too — But Not Like Humans

Dogs regulate body temperature differently than humans. While we sweat all over, dogs primarily sweat through their paw pads. When a dog is overheated, moisture can appear on the pads, sometimes leaving wet footprints. This sweat helps cool the body, but it can also trap humidity, especially if fur mats between the toes. That trapped moisture creates a breeding ground for bacteria, which may lead to irritation or infection — both of which can make paws feel hot.

Hot Pavement and Urban Hazards

Dogs’ paw pads are tough and designed to handle rough terrain, but they’re not built for city sidewalks. Walking on hot pavement — especially in summer — can burn a dog’s pads, causing them to feel unusually warm or even painful. Chemicals like ice-melting salts and sidewalk cleaners can also stick to paws, leading to irritation and heat-related discomfort. These substances may even taste sweet to dogs, tempting them to lick their paws, which can worsen the issue.

Infections and Inflammation Can Cause Heat

A paw that feels hot to the touch may be a sign of infection or inflammation. The paw pads are rich in nerve endings, so any injury, swelling, or abscess — such as from a bite — can cause localized heat and pain. According to diagnostic massage guidelines, heat in a paw could signal an infection, especially if the dog is limping, avoiding weight on the leg, or showing signs of fever. Bacterial growth from trapped moisture between toes can also lead to inflammation and warmth.

When Hot Paws Might Signal a Bigger Problem

While heat in the paws is often due to external causes, it can also reflect internal health issues. For example, if a paw feels cold instead of hot, it may indicate blocked circulation. However, persistent warmth — especially when paired with redness, swelling, or changes in fur — could point to systemic problems like hormonal imbalances. Though not directly linked to paw heat, thyroid insufficiency can cause skin changes and loss of fur, which may be detected during a paw check.

How to Care for Your Dog’s Paws

Regular paw care is essential. After every walk, wipe your dog’s paws to remove debris, chemicals, and heat-trapping dirt. Use a pet-safe paw balm to protect pads from extreme temperatures and chemicals. Keep the hair between toes trimmed to prevent matting and moisture buildup. If your dog licks their paws frequently, it may be a sign of irritation — clean the paws and monitor for signs of infection. Gentle paw massages can also help you detect abnormalities early.
