I have wormed my dog
recently with products from my vet. How would my dog get worms in
the future and what does the vet look for in a stool sample?
Dog parks can be a source of contact with contaminated feces
Mesocestoides are not worm organisms. They can be identified in
stool analyses and are single celled organisms.

eggs... kinds of worms... dogs and cats
roundworms, hookworms and whipworms are the most common intestinal worms
in dogs and cats in the USA. Each has a unique life cycle and all
can impact your pet's health. Intestinal worms are usually
contracted via ingesting infective eggs from another animal's stool or
during self-cleaning when egg-contaminated soil or feces is licked
from the fur or paws. Tapeworms usually are spread via ingestion of
fleas that have eaten tape worm eggs, or by ingestion of small animals
such as mice or rabbits that themselves have intestinal tapeworms.
Below is a list of common intestinal worms seen in dogs and cats:
Toxocara canis... adults are present in the small intestine of the dog and fox;
infection is via oral, transmammary and transplacental routes.
Infective larvae migrate through tissues, including to the fetus where
they can establish a prenatal infection!. They eventually pass
through the lungs and then to the alimentary tract. In hosts other than
the dog and fox, migration of larvae occurs but the life cycle is
not completed in the intestinal tract. Is the cause of ocular and visceral larval migrans in
Toxascaris leonina... are found in the small intestine of dogs, cats, foxes and wild
carnivora. Causes toxascariasis.
are found in the small intestine of the cat.
the most common hookworm of dogs.
fox, possibly humans
and feline hookworm

The whipworm called Trichuris vulpis usually affects dogs
and rarely the cat. It attaches to the cecum, a blind ended pouch at
the start of the large intestine (colon). It is a very tiny worm of no
longer than two inches in length. Dogs
and cats can be infected with a whipworm called Trichuris
trichiura. Whipworm eggs can live in an environment for up to a
few years and are present in soil, food, or water, animal feces or animal
LUNGWORMS and BLADDER WORMS
are occasionally found in urine sediments from cats and dogs.
They can be mistaken for eggs of Trichuris vulpis (whipworms) from
Capillaria aerophila and
abstrusus are parasitic nematodes; these two kinds of lungworms in
cats are common worldwide.
Taenia pisiformis... is a type of tapeworm found
in the small intestine of the dog, fox, and other wild carnivores, and
very rarely in cats. The infective stage, Cysticercus pisiformis,
can be present in rabbits' liver and peritoneal cavity.
a world-wide parasite that requires a flea as part of its life cycle to
develop fully. Depending on the presence of appropriate flea and
vertebrate hosts the eggs can survive outside of the host if conditions
Echinococcus multilocularis... although rare in dogs in the United States, cases have been
reported in California, Arizona, New Mexico, and Utah. Humans become
infected when they swallow eggs in contaminated food. The infection is
carried to the liver where cysts form.
