To find out where a dog's thickest skin is located, we firstly need to learn more about a dog's skin and the difference between thin and thick skin.

A dog's integumentary system comprises the skin, hair, claws, pads along with the  sebaceous, sweat and mammary glands. As it happens in humans, there are areas with thinner and thicker skin. 

What primarily makes the different between thin and thick skin is its layers. Some body parts simply require more thickness than others. 

Dog Skin Versus Human Skin

The thickness of skin varies between one species and another, but on average, it is estimated that the thickness of a dog's skin ranges from 0.5 to 5 mm. 

A dog's skin is thinner and much more sensitive than ours, states the Merck Veterinary Manual. 

Some of us may find this surprising, but turns out, our skin is three times thicker than our dogs' and our pH is different too, which is why we shouldn't use human shampoo for our dogs, explains Karen L. Campbell, a veterinarian specializing in dermatology in the book "The Pet Lover's Guide to Cat and Dog Skin Diseases."

On the other hand though, dogs have a coat, so there seems to be a convenient trade-off: generally, the more hair, the thinner the outer layer of skin. 

This is also seen on the dog to some extent. For instance, in  areas where dogs have less fur, you may notice how they have thicker skin. 

While our dogs may have thinner skin compared to us, there's an area of the dog's body where the skin is much tougher compared to the dog's other areas. Read on to discover more on it.

So Where is a Dog's Thickest Skin Located?

Knowing where a dog's thickest skin is located is an interesting query. Many assume that just because we lead dogs by their collars, they must have very thick skin on their neck, but turns out, there are certain area with thicker skin.

Sure, it is true that a dog's skin is thicker on the back and upper neck and that it becomes increasingly thinner toward the abdomen, being thinnest in the armpit, eyelid and inguinal areas, but a dog's thickest skin is ultimately found on the dog's paw pads. 

Ever wondered how dogs are able to walk in the snow, hot pavement or over the hard surfaces such as asphalt without having to wear shoes? This is all courtesy of those tough paw pads. 

Sure, if we were to walk barefoot for most of our lives, the skin on the bottom of our feet would surely toughen, but until the day we decide to ditch our shoes, we will be prone to have softer feet with more delicate soles.

 Other than protecting a dog's feet from abrasive surfaces and hot and cold temperatures, a dog's paw pads act as shock absorbers for all the bones, tendons and ligaments found on the dog's legs.

A Lesson in Dog Anatomy 

What does a dog's paw pad anatomy look like? Let's take a very close look at this body part and discover more about its components. 

The skin on a dog's paw pads is extra thick and not found in any other area of the dog's body. It's made of layers of insulating fat and connective tissue making them the perfect version of Mother Nature's insoles.

The outermost layer is the one we're most familiar with, it's called the stratum corneum and it's the hairless pigmented layer we see when we look at our dog's paws.

Different Types of Pain in Dogs

There are different types of pain in dogs and differentiating one from another can help you better understand your companion.

If you ever looked at your dog's paw pads very closely, you might have noticed how the outermost layer is made of small conical papillae. These papillae are made to add further protection.

You may have also noticed how the central surface of your dog's pads may be smooth compared to the outer edges.

This is from long-term walking on rough surfaces such as concrete. The smoothness is due to the conical papillae being flattened out rather than being conical due to abrasion, while the papillae on the edge remain conical.

Dogs who tend to walk more on hard surfaces and are older tend to generally have tougher paw pads than dogs used to walking in grass and carpet and who are younger.

Did you know? A dog's foot pads contain many blood vessels which is why they tend to bleed easily when injured.

Strong, But Not Invincible

While a dog's paw pads are pretty tough and able to withstand the many miles dogs put on their feet, consider though that this doesn't mean you can walk your dog over hot asphalt or over ice melt without having any problems.

A dog's paw pads can be prone to cracks, abrasions, ulcers and blisters when exposed to heat and cold, harsh surfaces and chemicals.

Most commonly, the dog's outer layer of skin, the stratum corneum sloughs off, exposing a raw layer of skin that is very sensitive and can take even weeks to properly heal.

In nature, injuries to a canine's feet can have deleterious effects and may strongly incapacitate these cursorial animals who need to run to hunt for prey and run away from predators. 

Luckily, in a domesticated setting, we can take care of our dogs providing them food and resting their feet as needed, which gives time for their paw pads to fully heal.

Paw pads are prone to healing slowly because they're more exposed to contaminated surfaces. Dogs need to walk on them and dogs are prone to further aggravate the area through persistent licking and chewing. 

Fortunately, we can do a whole lot in preventing injuries from occurring in the first place such as inspecting a dog's paw pads on a routine basis after exercising on rough surfaces, and avoiding temperature extremes or exposure to harsh chemicals and irritants. 

Also, keeping a dog lean will help put less pressure on the toes and joints so the dog is "lighter on his feet."

Did you know? Because the tissues on a dog's paw pads is highly specialized and has precise functions, it's irreplaceable, and therefore cannot be replaced from other skin from the body, explains Dr. Tannaz Amalsadvala, 

Conditions Causing Skin Thinning in Dogs

Interestingly, certain medical conditions in dogs have been associated with skin thinning. In particular, dogs suffering from Cushings' disease have been reported to have thinner skin due to decreases in total skin collagen.

 In one particular study, skin thinning was found in  60 percent of dogs with Cushings', with their mean skin thickness being 25 percent less than normal.

 On top of Cushings', dogs who were taking topical or oral steroids were found to develop skin thinning. 

Did you know? According to a study which evaluated skin thickness in 5 different breeds, the thickest skin was found in Labrador retrievers while the thinnest was found in poodles. However, according to Miller's Anatomy of the Dog, the greatest skin thickness of all is found in the Chinese Shar-pei.
