How to Tell if Your Dog Has Hookworms

Hookworms are parasites that live in a dog's intestines. The hookworm feeds on the dog's blood and injects its eggs into the dog's digestive system. Dogs generally pick up hookworms through contact with infested soil, says the Companion Animal Parasite Council. Hookworms affect dogs of all ages but are especially dangerous to puppies, as the internal blood loss will make the puppy anemic. Vets should treat puppies for hookworms at 2, 4, 6 and 8 weeks old. Prescription monthly heartworm preventatives often protect dogs of all ages against hookworm. Recognizing the signs of a hookworm infestation can help reduce the medical effects on the dog.

Instructions

    • 1

      Watch your dog to see if its feet are more itchy than usual. See if your dog is biting or chewing its feet to relieve the itch, and check the paws to see if they are red or have a rash.

    • 2

      Listen to your dog's breathing. Hookworms make dogs wheeze and cough.

    • 3

      Check your dog's stools for consistency. Diarrhea is one of the symptoms of a hookworm infestation. Look for bloody or tarry-looking stool. Watch your dog when it is defecating to see if it appears to be in any discomfort, which could also signify hookworms.

      Watch your dog to see if it appears nauseous. Look for unproductive retching or vomiting, especially if it occurs more than once or twice.
