Parasite Prevention for Dogs

Parasites are pesky little organisms that can be found almost anywhere year-round, so they’re incredibly common. The vast majority of pets will contract a parasite at least once or twice during their lifetime, which is why parasite prevention for dogs is so important. A walk along your favorite hiking trail or a visit to the local dog park could expose your pet to all kinds of creepy crawlies.

Parasites feed on other organisms to survive, and if a parasitic infestation is left untreated, your pet could suffer from severe, long-term complications. And if that’s not enough to make your skin crawl, some parasites are zoonotic — they can transfer from your pet, to you and your family. Protect the wellbeing of both your four-legged and two-legged family members by following this handy parasite prevention guide.


External parasites

As the name suggests, external parasites are organisms that live on the outside of your pet. Fleas and ticks are perhaps the most well-known of the external parasites, but lice and mites also fall under this category. While external parasites may only cause mild skin irritations, they can also cause extreme discomfort for your pet and transmit serious diseases like Lyme disease.


Signs of external parasites in dogs

It’s always a good idea to stay up to date on your pet’s flea and tick prevention medications, but in the meantime, the following signs could indicate that your pet brought home an unwanted guest:

  • Generalized hair loss, or an overall thinning of your pet’s coat

  • Intense itching and/or licking

  • Excessive head shaking with brown or black ear discharge (sometimes caused by ear mite infestations)

  • Scaly skin patches

  • Skin irritation

  • Anemia (weakness, lethargy, decreased appetite)

External parasites can wreak havoc on your pet’s health if left untreated. One flea may not seem like a big deal, but these bugs can lay up to 50 eggs a day, and an adult female tick can consume up to 100 times her weight in blood.

A mild external parasitic infestation can turn problematic very quickly, so if you notice any of the above signs, give your veterinarian a call.


Internal parasites

Most internal parasites are worms that live in the intestinal tract of your pet and include roundworms, tapeworms, and hookworms. Giardia and coccidia also fall under this category and are extremely contagious among dog and cats.

Internal parasites are especially dangerous to the growth and development of puppies and kittens. Likewise, internal parasites can quickly become life-threatening for pets with weak immune systems.


Signs of internal parasites in dogs

Internal parasites are usually found in a dog or cat’s stool. Every pet should have regular fecal exams, but your veterinarian may recommend more or less frequent testing depending on your pet’s lifestyle and whether you’re diligent with regular deworming.

Keep an eye out for the following signs of internal parasites in pets:

  • Diarrhea

  • Constipation

  • Vomiting

  • Lethargy

  • Blood in stool

  • Weight loss

  • Decreased appetite

  • Excessive coughing

  • Scooting

  • Distended/bloated abdomen

  • Worm segments in fresh stool and/or bedding (they may resemble grains of rice)

Pets infected with intestinal parasites may not show any symptoms, so keep your dog or cat parasite-free by taking them to the veterinarian at least once a year for regular check-ups. Remember almost all puppies receive their first infestation from their mothers milk (eggs lay dormant untill brest milk is produced- then lava are ingested by infant puppies.). If you suspect the presence of an internal parasite, give your veterinarian a call right away.


How to prevent parasites in pets


The most reliable way to prevent parasites is through year-round heartworm, flea, and tick prevention medication, as well as annual physical exams by your veterinarian.

These measures will certainly help prevent parasites, but they’re by no means foolproof, so here are some additional parasite prevention tips.


Practice good hygiene

Certain parasites are highly contagious and easily passed between pets and humans, so good hygiene is crucial — especially with young children in the home who are known to put everything in their mouths. This also includes washing your hands after touching your pet or cleaning up after them, regularly washing their bedding, frequently vacuuming any carpeting in the household, and giving your pet a bath if they become soiled.

Clean up after your pet

Since many internal parasites are transmitted through feces, clean up your pet’s waste promptly. You may also want to avoid areas where poor hygiene is practiced, such as dog parks where people might not regularly clean up after their pooch.

The risk of contracting Giardia is more common in overcrowded places like shelters, kennels, and dog parks, and is most frequently contracted from drinking water contaminated with fecal matter.


Avoid natural remedies and raw food diets

Avoid feeding your pet a raw food diet, as it may put them at a higher risk of contracting parasites and bacteria. If your dog brings home a mole, small rodents, or birds, you need to have parasite control in place.

Pet parents also shouldn’t rely on natural remedies for parasite prevention, as they’re not effective and can sometimes make your pet sick. Always consult with your veterinarian before starting your pet on a raw food diet or natural parasite remedies.


Check your pet for parasites after coming inside

Anytime you come indoors after being outside with your pet, carefully check your friend for external parasites. The area around your pet’s collar, groin, and head are the most common places that attract parasites. Ticks start small but grow larger the longer they feed on your pet, so continue checking your pet for several days after coming home from a long hike or camping trip.

If you discover a tick on your pet, don’t panic! Removing ticks is straightforward and painless for your pet if you know what you’re doing.


Learn about parasites in your area

Visit the Companion Animal Parasite Council to learn about parasites in your area. The prevalence of parasites can change depending on your geographical location and the time of year, so a little research can be a real life-saver when it comes to parasite prevention.

Consider pet insurance

While parasite prevention and control is typically not covered by pet medical insurance, having good coverage in place can help lessen the worry overall about your pal’s health. By covering new, unexpected pet health expenses, pet insurance allows you to focus on your pet’s care rather than your finances.
