How do you know if a dog has hookworm?

Your dog’s been licking their hind legs nonstop lately, a habit that started after that rainy afternoon at the community dog run. At first, you figured it was just mud or a stray burr bothering them. But when they turned away from their favorite treats this morning, you felt a twinge of worry. Those little shifts—odd licking patterns, sudden disinterest in food—might be early hints of hookworm, a parasite that thrives in damp, grassy spots like the ones your pup loves to explore.

Dogs with hookworm often show subtle signs at first, but those small changes can escalate quickly if left unchecked. Watch for persistent scratching or licking of their paws and belly—these tiny parasites latch onto the intestinal wall, causing irritation that makes your pup uncomfortable. You might notice their coat losing its shine, becoming dull and brittle, even if their diet hasn’t changed.

Another red flag is unexpected weight loss, especially in puppies. Hookworms feed on blood, robbing growing dogs of essential nutrients. A once-energetic puppy dragging their feet during walks or skipping meals could be fighting an infestation. Keep an eye on their stool too; loose, dark, or bloody diarrhea often points to these unwelcome guests.

Puppies are particularly vulnerable, as they can pick up hookworms from their mother’s milk or contaminated soil. If you see a young dog with pale gums or lethargy, it’s time to act—severe infestations can lead to anemia, a serious condition that needs prompt veterinary care. Adult dogs aren’t safe either; they can contract hookworms by sniffing or rolling in infected areas, or even through their skin.

Don’t wait for symptoms to worsen. Regular vet check-ups, including fecal tests, are key to catching hookworms early. Many heartworm preventatives also tackle hookworms, so ask your vet about a year-round plan that fits your dog’s lifestyle. This isn’t just about your pet’s health—some hookworm species can affect humans too, causing skin irritation or more serious issues, especially in children.

In many regions, local laws require keeping pets free from parasites that pose public health risks. Failing to treat hookworm infestations could land you in hot water with animal control, not to mention putting your community at risk. Responsible pet ownership means staying ahead of these pests, not just reacting when problems arise.

If you suspect hookworm, visit your vet right away. They’ll run tests and prescribe dewormers that target these specific parasites. With prompt treatment, most dogs recover quickly, returning to their playful selves in no time. Remember, a little vigilance goes a long way in keeping both your furry friend and your family safe from hookworm troubles.
