A reader wrote in with a question about little black bugs on a dog:
“My dog has lost hair in spots and is scratching a lot. I see little black bugs on him. He is white and very fuzzy, what could this be?”
Finding little black bugs crawling on your dog is never a nice surprise! There are several types of little black bugs that can crawl on dogs that I’ll discuss in this article.
The most likely thing little black bugs on your dog could be is fleas. If you’ve never seen a flea, they’re about ⅛ of an inch long, sort of flat on the sides, dark brown and they tend to scurry and jump. There are other little black bugs that can crawl on dogs that I’ll discuss in this article.
Fleas are extremely common and often cause scratching that is worse right above the dog’s tail on his lower back area.
One easy thing you can do right away to get rid of bugs on your dog is to simply give him a bath using regular dog shampoo. Bathing won’t get rid of ALL the bugs, but it should help decrease their number a bit until you can get to a veterinarian and find out exactly what those little critters are.
Even if the little black bugs on your dog are not fleas, rest assured most of these parasites are not too difficult to get rid of if you take the right approach.
Four Common Kinds of Little Black Bugs on Dogs
Fleas are the most common dog skin parasite and are large enough to be seen without a microscope. If your dog only has a few fleas, it might be tough to find them. You can also look for flea “dirt” which looks like black sand in the fur which turns red if dabbed with a wet tissue (it’s actually flea poop).
Fleas cause a lot of scratching and are worse during warm seasons. There are many safe and effective ways to get rid of them. Don’t forget to treat all of your pets, your home and your yard if you want to beat fleas.
Ticks range in size from about 1/32 of an inch all the way to 1+ inches when engorged. The small ones are often called “seed ticks” and I’ve seen dogs with literally dozens of them.
Ticks are the second most common external parasite we see on dogs. Ticks can transmit blood parasites to dogs and humans, so it’s really important to get rid of them A.S.A.P.!
You can remove them manually using tweezers. Grasp the tick with the tweezers as close as possible to the dog’s skin and gently pull away.
It’s best if you can get the tick’s head and not leave it embedded in the skin but that’s not always possible. If the tick’s head is left behind, watch the area for significant inflammation and get your vet’s help if you notice this.
Another option is to use a topical medication or an oral medication. Frontline Plus® and NexGard® are popular tick control products many of my clients use for their dogs.
There are a bunch of different kinds of mites that can infest dogs.
One of the ones that are big enough to be seen without a microscope is Cheyletiella, also called “walking dandruff” as they are very tiny (less than 1/32 of an inch) but look like specks of dandruff moving among the dog’s fur.
I don’t have a photo of Cheyletiella mites on dogs, but I can tell you they look more whitish than black.
If you part the dog’s fur and watch closely, you’ll notice what looks like small flakes of dandruff but it moves a little bit.
Unlike fleas that race around quickly, Cheyletiella mites move slowly. Check out some Cheyletiella photos on Veterinary-Practice.com.
Other mites that come from birds and rodents usually look blacker than Cheyletiella. It’s possible for bird or rodent mites to infect your dog, but it is not a common problem.
Cheyletiella mites can make your dog really itchy. Plus they can infect humans. The good news is that they’re pretty easy to get rid of. Mites are much less common than fleas and ticks.
Lime sulfur dip (make sure to dilute it) and Frontline Plus are both effective against Cheyletiella mites. You’ll want to clean your home and bedding really well and consider calling an exterminator, too.
Lice are tiny but they are visible to the naked eye. About 1/8 to 1/4 inch in length, lice are less common parasites of dogs in North America. They can appear whitish to dark brown in color.
Lice attach their eggs to the hair shaft and you can see these “nits” if you look closely at the base of your dog’s hair shaft. They also cause a lot of scratching and are highly contagious to other dogs, but not to humans.
They’re relatively easy to get rid of, too, thank goodness! You can get rid of lice by using lime sulfur dip, neem oil shampoo, or Frontline Plus.
Bonus: Non-Parasitic Little Black Bugs
There’s always a chance the little black bugs you’re seeing have just “hopped on” your dog but aren’t causing any problems.
There are so many bugs in the environment, that it’s impossible for me to list them all.
Your best bet is to collect one or more of the bugs (try using cellophane tape), put it in a closed container and take them to your vet.
Your veterinarian can look at it with a microscope to identify it. Then they can recommend the safest, most effective treatment to rid your pup of little black bugs.
Getting Rid of Little Black Bugs Dogs
Modern science has developed dozens of chemicals used to kill and repel parasites on dogs. A few of the most popular parasite control products for dogs use fipronil, imidacloprid and afoxolaner.
Most of them work by disrupting the parasite’s nervous system. Since parasite nervous systems function differently than dogs’ nervous systems, the chemicals have negligible effects on dogs.
Some of us don’t like the idea of putting any chemicals in or on our dogs if more natural methods will work. Natural methods will work against parasites, but they’re not nearly as strong or as fast as typical anti-parasite drugs and chemicals.
For natural methods of parasite control to work, you must be willing to put in the work and repeat it as often as necessary until all the bugs are gone!
FAQs from Readers
If I wash and brush my dog will it get rid of what I think is either mites or ants?
Most true parasites are not easily removed during a standard bath and brush. A bath could be effective at removing non-parasitic “bugs” like ants. If your vet can identify the little creepy critters, you can get a specific treatment to get rid of them!
Are these bedbugs on my dog?
Bedbugs prefer to hide in bedding but could potentially crawl onto a dog for a short time. Bedbugs are brown-red parasitic insects that are about 1-7 mm in length. Their preferred meal comes from humans, but they can bite dogs, too.
