Why Do Dogs Get Fleas?

Lets start at the beginning. 

Fleas. Tiny insects that feed on your darling pets blood and live within its fur are disgusting. 

What makes dogs so attractive to fleas? 

Fleas are attracted to dogs for a number of reasons. 

A dog is a very social creature. 

They usually enjoy exploring the outdoors sniffing around in bushes and weeds and interacting with other dogs they meet. 

Due to their ability to jump so far fleas can easily jump into your dogs fur from nearby plants the ground or even another pet. 

It is because of the innate attraction fleas have to heat carbon dioxide and vibration that they love to target dogs specifically. 

Warmth and movement are important to them. 

Typically a dog will check each of these boxes moving around breathing heavily and generating heat as they do so. Fleas love the fur on your dog! 

What is Flea Dirt?

Now that we know why fleas attack dogs lets look at flea dirt. Get ready to be disgusted.

Flea dirt is a combination of blood meal and flea waste.

Its basically flea feces. 

Usually you can see small round black specks on your dogs skin that look like flea dirt.

Fleas are usually found in the rear area of your pet so you’ll see more of these black spots around their tail groin or hind legs.

Though they are known to avoid the head and neck flea dirt may still accumulate there sometimes. 

Why Do I See Flea Dirt But No Fleas?

Your pet might have a few flea dirt specks but no fleas to accompany them.

There are a variety of causes for this.

They may have eaten them while self-grooming which is more common in cats than in dogs or they may once have been present but have now jumped off and relocated elsewhere. 

Only a small portion of fleas’ lives are spent on your pet.

In their pitifully short lives they only stay to feed and lay eggs then they move on.

This process can happen fairly quickly since fleas only live on average for eight days. 

How Can I Test for Flea Dirt?

You may want to conduct a flea test if you see dark spots on your pets skin but are not sure if they are flea dirt or normal dirt.

Using a flea comb remove some of the dark marks from your pets fur and place them on a lightly wetted paper towel.

Fly dirt dissolves and turns a reddish-brown color if it is really flea dirt. Ordinary old dirt remains brown.

To remove specks you can also rub the wet paper towel across the spots to achieve the same result. 

Do Fleas and Flea Dirt Tend to Collect in One Particular Place on a Dog’s Body?

Yes this is the answer to the question.

As previously mentioned fleas prefer to nest in the rear areas of your dog.

The tail groin and hind legs are all included in this.

You may find them around the ears neck and front legs of your dog but they tend to stay away from the front end. 

When checking for fleas or flea dirt on your dog make sure you check every inch of his body as an untreated flea infestation can quickly become a serious problem. 

Is Flea Dirt Harmful to Humans?

All of this might freak you out a little isnot it?

Donot worry you are not the only one wondering if flea dirt is harmful to humans.

Flea dirt does not pose any serious health risks to humans but those in contact with it can develop allergic dermatitis.

This is typically accompanied by inflammation and itchy skin at the point of contact but this will not always occur.

It may not have any effect on you. Thats great!

How Do You Get Rid of Flea Dirt on Your Dog?

If your dog has flea dirt on it the first step is to scrub it thoroughly in the tub with an anti-flea shampoo.

If you are looking for a high-quality solution for your dog remember to leave it on for 5 to 10 minutes before rinsing. 

After washing and rinsing them you should take a flea comb to their fur and comb through every inch.

Fleas cannot be tracked for long distances so you have to be very thorough if you want to get rid of them. By removing the flea dirt you will kill any fleas that may have survived the bath. 

You may need to see a vet if the problem persists so that he can prescribe an anti-flea medication.

In no time at all you will be rid of those pesky pests with this method.

Oftentimes though a thorough cleaning routine can remove the problem entirely in as little as ten days! 

How Do You Get Rid of Flea Dirt in Your House? 

Make sure the flea dirt and fleas are gone by removing all bedding and pet bedding and washing it in an anti-flea solution. Make sure hidden areas are exposed by moving furniture. If you see flea dirt accumulating vacuum the area as the suction will remove the dirt and expose the eggs. 

You should repeat these steps every other day for at least 10 days if the problem persists. Depending on whether the problem persists you may want to extend the process. Those who live in heavily carpeted homes may need to steam clean after vacuuming since fleas may still be hiding deep within the carpet threading. Keeping things clean is especially important if you live in a warmer climate as fleas thrive in the heat. 

In the case of an especially bad problem chemical treatments are always available. Depending on your needs you can either treat your home yourself with a flea bomb you can buy at a local retailer or hire an exterminator to handle the issue for you. Getting rid of fleas and their dirt will be a huge relief once you have done this. 

What Looks Like Flea Dirt (But Isn’t)?

Lets take a look at a few harmless things that could be mistaken for flea dirt. Lets start with the obvious regular dirt. Yes those little dark specks on your dogs fur or skin might just be dust that got stuck there while your dog was outside playing. You can clean your dogs ears by rubbing soap and water over them.

Upon closer inspection you’ve determined that the black specks on your dogs fur are neither flea dirt nor regular dirt. Why are they there? It is likely that these are actually tiny scabs caused by flea allergy dermatitis.

Despite the fact that fleas and flea dirt have been removed these can still appear on your dogs coat and skin. 

Some roughhousing may also cause scabs. This deceptive scabbing may be caused by tiny thorns or branches in thickets that your dog likes to run through. In this case you do not need to treat the scabs since they will naturally heal over time. To prevent this from happening again shorten the leash on your dog!


In addition to their presence fleas leave behind a lot of nasty stuff. We hope this article has given you enough information to determine what those tiny black spots on your dogs skin are and how they can be removed. 

Keep in mind that an unchecked flea infestation can become a major problem if left unattended. They can affect not only the quality of life of your pet but also yours! In a matter of minutes your home could be crawling with these nasty pests so its best to treat your pet and house at the first sign of flea dirt.
