Hookworms

Hookworms are very small worms that have hook like mouth parts that burrow into your dog's intestinal wall and suck blood. They can cause anemia, black or bloody diarrhea and sometimes death in puppies. Diagnosis is made by examining the feces for eggs under a microscope

Most often found in humid tropical areas. Can infect humans.

Roundworms

Dogs can become infected with roundworms by eating infected lizards, mice, birds and other prey. Puppies can be infected by their mothers. They can also become infected from ingesting soil contaminated by infected faeces. If your puppy vomits up a worm there is a good chance it is a roundworm. Roundworms will look like spaghetti in the puppy’s feces.

Roundworms can be passed on to humans and children are most at risk.

Whipworm

Often hard to diagnose from a stool sample. Chronic weight loss may be a symptom of whipworm together with feces that has a covering of mucous.

Whipworms are not passed on to humans.
