Parasite Reference

Parasite Type	Common Species	Characteristics & Clinical Relevance
Nematodes (Roundworms)	Toxocara canis	Large, spaghetti-like worms. Zoonotic potential (Visceral Larva Migrans, Ocular Larva Migrans). Common in puppies (transplacental/transmammary transmission).
	Toxascaris leonina	Less common, generally less pathogenic than T. canis. No zoonotic potential.
Nematodes (Hookworms)	Ancylostoma caninum	Blood-feeding, can cause severe anemia, especially in puppies. Zoonotic potential (Cutaneous Larva Migrans). Transmammary transmission.
	Ancylostoma braziliense	Primarily causes Cutaneous Larva Migrans in humans; less pathogenic in dogs.
	Uncinaria stenocephala	Less pathogenic than A. caninum, but can still cause anemia. More common in cooler climates.
Nematodes (Whipworms)	Trichuris vulpis	Resides in the cecum and large intestine. Causes chronic large bowel diarrhea, often with mucus and fresh blood. Eggs are highly resistant in the environment.
	Trichuris campanula	Less common, similar pathology to T. vulpis.
Cestodes (Tapeworms)	Dipylidium caninum	Most common canine tapeworm. Requires ingestion of infected fleas. Proglottids resemble rice grains.
	Taenia pisiformis	Requires ingestion of infected lagomorphs (rabbits). Less common than D. caninum.
	Echinococcus granulosus/multilocularis	Small, highly pathogenic tapeworms. Significant zoonotic potential (Hydatid Disease). Requires ingestion of infected intermediate hosts.
Protozoa	Giardia spp.	Flagellated protozoan. Causes giardiasis (diarrhea, malabsorption). Not a "worm" but often treated with dewormers like Fenbendazole.
