Painful Fluid-Filled Blisters!
Not only you but even your dog can get a blister on dog paws. And these are not limited to minor fluid-filled Blisters but can also get dog paw blood blisters. The reason for this could be an injury or something else.

Dog’s paws are a very crucial part of their body. From standing, walking, jumping, and running, these paws serves dogs in everything. Therefore, they will most likely get harmed and have blisters. As a pup’s parent, you should inspect your puppy’s footpads every few days. Cleaning them and checking for blisters is a regular inspection routine. Even if you are not examining, a change in your dog’s walk will depict that there is something wrong with their feet.

Blister on Dog's Paws Causes and Treatment

What does Dog Blister look like?

Just like in Humans, the Dog blister is some liquid-filled Bubble protruding on the skin surface. These blisters are mainly found in hairless regions such as paws. These blisters can vary in shape from oval to round. Instead of a single large jutted blister, you might spot tiny blisters on your dog’s paws. The blister formation is quite an interesting phenomenon. When the uppermost layer of a dog’s skin separates from the deeper layers, it forms a hollow space, which the body fills by pouring out some liquids. Vets consider a skin lesion to be a dog paw blister if it is filled with some clear liquid or serum. This clear liquid is filled with white blood cells. Sometimes, instead of serum, Blisters are filled with pus. These blisters are called Pustules. These Pus-filled blisters mainly constitute dead tissues, cellular debris, and WBCs too. Due to friction, these blisters can burst and cause infection, inflammation, or ulcers-the empty skin craters.

What Causes Dog Paw Blisters?

what causes dog paw blisters
The primary reason for a blister on dog’s paw pad is FRICTION. When the dog moves its feet on the ground, friction and heat are produced. It results in the formation of blisters. These blisters are more likely to occur when a dog moves more on rough surfaces like gravel, pavement, etc. Common reasons for sores on dogs’ paws:

Due to Allergies

Due to seasonal or even food allergies, dogs continuously lick their paws. This continuous licking habit can cause blisters and infections too. Therefore, it’s crucial to take extra care of dogs during allergic seasons and continuously check if they are not allergic to some food item.


Dog feet injury sometimes causes blood blisters on dog paws. The damage is usually caused by some sharp objects that, in turn, form blood blisters. These are the excruciating types of blisters.

Rough Surface

Rough surfaces like rocks, hiking trails, cracks on the road, gravel roads, and construction sites can cause blisters on dogs’ paws. So, ensure the surface is clean and decent to step on for your dog before dragging them over a walk.

Extreme Training

Dog parents sometimes become too extreme with the training, and even the dog performs beyond its limits to impress its owner. In such cases, dogs can get blisters. If you are also a pooch parent, you have to understand your dog’s limits and don’t overdo the training.

Skin Irritations

Especially in winter, roads are covered with chemicals and salted roads. In such conditions, when you take your dog outside, your dog might develop blisters due to these chemicals. So when you are back home, make sure to clean your dog’s paws in such a scenario.

Hot Surface

Unlike you, dogs don’t wear shoes and can feel the heat or even harm from walking on hot roads in the summers. The blister is just the minor damage that a dog pays while walking on a hot surface. In extreme cases, dogs can also get heatstroke. So make sure to check the surface temperature before taking your dog outside.


Cysts are different from that from blisters. One should know the difference between them and don’t mistake one for another.
