How To Spot And Treat Fleas, Ticks, And Lice

The sad price of a dog’s iconic cuddly coat is that it leaves them vulnerable to parasites. Our pups are more likely to come into contact with fleas, ticks, or lice. While the idea of tiny creatures crawling around our dogs seems gross, external parasites are preventable and treatable.

The key to keeping your dog parasite-free is preventive medications and knowing how to spot each parasite. If you can detect them early on or stop them from clinging to your pup at all, you can help prevent your dog from getting sick. Here are the three major external parasites that can affect dogs, and how to detect and treat them.

Fleas

Fleas are reddish-brown and about the size of a pinhead. It’s difficult to spot these tiny insects unless you see them running or jumping on your dog. They are frequently found in the groin, armpits, and ears.

Fleas are more common during the warmer months or in warmer climates. However, since they can continue their life cycles indoors, it’s possible to spot fleas in the winter.

How To Tell If Your Dog Has Fleas

If there is one thing fleas are good at, it’s making your dog itch. Constant scratching can cause visible patches of hair loss on your dog, as well as reddened and irritated skin. Fleas can cause skin allergies as well. In some cases, they can even transmit other parasites like tapeworms to your dog.

To tell if your dog has fleas, look for “flea dirt.” Flea dirt is the black flecks that fall from a flea-infested dog. Since fleas are sucking your dog’s blood, they’re also producing it in their waste. When those flecks get wet, they’ll turn red or rust-colored.

To find “flea dirt,” have your dog sit or lie on top of a white piece of paper. Then, briskly comb or rub a section of the hair on your dog’s back. If your dog does in fact have fleas, the flea dirt will fall onto the paper. Now you just have to dampen the paper and observe any color change.

How Do You Treat Your Dog For Fleas?

When in doubt, you should always consult your veterinarian. They’ll be able to assess the situation and recommend safe and effective products. Treatments vary but include:

  • Flea Collars
  • Sprays
  • Powders
  • Topical Spot Treatments
  • Ingestible Tablets And Liquids

Take care not to treat your dog near a cat if you have any. Dog flea treatments contain permethrin, which is toxic to cats. Make sure to keep your animals apart for a little while to avoid the risk of contact entirely.

Due to the nature of their life cycles, fleas can still hang around your home even if you treat your dog. This is because female fleas start laying eggs within the first 24 hours of choosing your dog as a host. They can lay about 50 eggs a day. Those eggs can then fall off your dog and onto the floor, furniture, or even outdoor areas where your dog lies. Non-adult fleas can remain dormant (or inactive) for weeks before they’re ready to infest an animal.

Vacuum your floors and clean the areas where your dog usually hangs out. Make sure to throw out the vacuum cleaner bag when you’re done too. That will help get rid of lingering flea eggs, larvae, and pupae. If your infestation is really severe, there are certain pet-safe insecticides you can treat your home or yard with. Consult your veterinarian if you aren’t sure what’s safe.

How Do You Prevent Your Dog From Getting Fleas?

Prevention methods for dogs range from pills to shampoos to topical spot treatments. It is strongly advised that you do not buy a product without clear knowledge of how it will affect your dog. Consult a veterinarian, who can recommend safe and effective preventive medications.

Ticks

Ticks are small, but you can still see them with your naked eyes. After they’ve bitten a dog and feasted on its blood, they swell in size, so they’ll be especially easy to spot then. You can also typically feel them when running your hands across your dog.

Since they attach themselves to your dog’s skin, you’ll need to look underneath their hair. It may be easier to do when they are wet. Ticks are most often found around your dog’s neck, in the ears, in the folds between the legs and the body, and between the toes. But they can be found anywhere on your dog’s body, so check everywhere.

Ticks can stay attached for several days. Finding and removing the tick right away is important because the longer a tick is attached the higher likelihood your dog gets ill.

Risks And Consequences Of Tick Bites

Ticks may carry several dangerous diseases, so it is important to regularly check your dog thoroughly for ticks.  Dr. Gary Brummet of the University of Illinois Veterinary Teaching Hospital says:

“Ticks are infamous for their disease-carrying capabilities. They transmit Lyme disease and Rocky Mountain spotted fever and can also pass along protozoa like Cytauxzoonosis and many others.”

Once a tick attaches, it takes 1-2 days for it to transmit the bacteria that cause Lyme disease. Prompt removal of a tick is absolutely vital! Often, signs of severe illness from tick bites may not show up for 7 to 21 days.

Symptoms of Lyme Disease in dogs include:

  • Fever
  • Loss of appetite
  • Painful or swollen joints
  • Lameness that comes and goes
  • Swollen lymph nodes
  • Lethargy

Lyme disease left untreated can lead to damage in the kidneys, nervous system, and heart. In addition to Lyme and Rocky Mountain Spotted Fever, ticks can cause paralysis. The risk of serious disease varies based on geography and the species of tick.

How To Remove Ticks And Treat Your Dog

When you find a tick, it’s crucial to remove the entire tick, including the jaws and head embedded in your dog’s skin. Crushing, twisting or jerking the tick out of the skin while its head is still buried could end up leaving the tick’s mouth parts in your dog’s skin. If the tick’s head is left behind, it can cause irritation or infection.

The best method for removing ticks is to grab their head with tweezers and pull slowly but firmly. After removing the tick, crush it but make sure to avoid contact with tick fluids that can carry disease.

Put the tick in alcohol to kill it once it’s been removed, but not before then. Smothering the tick in alcohol or petroleum jelly, or applying a hot match to it while it’s still attached might cause the tick to regurgitate saliva into the wound which could increase the risk of disease.

How To Prevent Ticks

If you know you live in an area where ticks are known to reside (such as forests or areas with thick brush), daily tick checks are the safest bet. You can prevent infection or illness by catching and removing ticks as soon as they appear. If you go on a camping or hiking trip with your pup, you’ll definitely want to be on the lookout.

If your dog picks up a tick in your own yard, you can trim bushes and remove brush to prevent your pup from coming into contact again. In this particular case, you should also check yourself for ticks and wear long pants in these spots.

The most important step to take is giving your dog preventive medications and treatments. The American Veterinary Medial Association (AVMA) warns dog parents that parasite protection is not “one-size-fits-all.” Certain products are not meant to be used on very young or very old dogs. Some breeds can be sensitive to certain ingredients as well and could become ill from preventive products. Remember: when in doubt, always consult your veterinarian.

Lice

Lice can be the most difficult pests to spot since they are much smaller than ticks and less mobile than fleas. They’re flightless insects that live in hair and feed on skin cells and excretions from their hosts. Lice tend to look like dirt, debris, or small brown rice on your dog’s coat, but they won’t wash out.

When they’ve found a host, female lice glue their eggs, called “nits,” to hair shafts near the skin. Nits are oval-shaped and translucent. When they hatch, the lice undergo nymphal stages before reaching adulthood. Typically lice will develop from nit to fully-grown adult in about 3 to 4 weeks.

How To Tell If Your Dog Has Lice

Excessive itching can be a sign that your dog is infested with fleas, ticks, or lice. Dry skin and allergies may also cause itching, so it doesn’t always indicate parasites, but it should cause you to take a closer look at your dog’s skin. They might have missing or matted patches of hair if infested with lice. A dog with lice will often have a rough, dry coat as well.

Animals that live in crowded or unsanitary conditions are much more likely to get lice. If you regularly attend to your dog’s coat and living areas, they’ll most likely avoid them. However, they might pick up lice at daycare or dog parks.

Risks And Consequences Of Lice

Because your pup will scratch and bite at its skin frequently, they may cause some damage. Scratch wounds can become infected. Sucking lice can cause little wounds which can become infected. Some lice can also serve as hosts for intestinal tapeworms.

Severe infestations, especially in puppies, can lead to anemia. Within a few months, a dog could lose about 1/4thof its blood to lice, which could even put them into shock.

One silver lining is, lice are usually species specific, so it’s not likely they’ll be transferred to you from your dog.

How To Treat A Lice Infestation In Dogs

First things first, consult your veterinarian. They’ll have the best knowledge of effective and safe products for your dog. Unfortunately, regular washing and shampooing will not dislodge lice nits. Lice that fall from their host will die within a few days. However, eggs can continue to hatch over 2 to 3 weeks.Your veterinarian can help you find lice specific shampoos and treatments.

Dogs and cats are usually treated for lice with spot-on products, lice shampoos, collars, sprays, or dust. Treatment will probably have to be continued for a little while to ensure that the adult lice and the larvae and eggs have all been killed. Typically, lice control treatments should be repeated 7 to 10 days after the first treatment. You should also continue to inspect your dog’s coat daily for at least 2 weeks after you see the last louse.

If treatment goes on for more than a week and the lice are still there, your veterinarian may suggest environmental control. Clean every brush, kennel, and piece of bedding your dog uses thoroughly with hot water. Bag up fluffy toys to isolate them. You should also take extra care to seal and dispose of any dead or live lice removed from your dog.

Preventing Lice In Dogs

There are a variety of lice prevention treatments for dogs out there. In addition to consistent treatment, don’t let any other dogs make contact with a lice-infested dog. That’s what spreads the lice.

If you consistently clean your dog’s space and possessions, they’ll be less at risk.

External Parasites: A Summary

  • If you find sufficient evidence that your dog has an infestation, consult your veterinarian for a safe and effective course of treatment.
  • Use preventive medications consistently to keep your dog safe.
  • If you live in areas of risk, perform daily tick checks on your dog.
  • Wash your dogs’ bedding and sleeping areas frequently.
