''U. stenocephala'' can be recognised on examination under a microscope by its large, dorsally curved, buccal capsule which contains cutting plates at the ventral edge.  A single pair of small teeth are also found within the ventral capsule.  Adults bury their heads deep in the wall of the small intestine and feed on plugs of mucosa.

Like almost all hookworm eggs, those of A. caninum are oval in shape and around 50 um in diameter. The shell membrane is thin and transparent and, by the time the egg is passed in the faeces, it contains a segmented ovum at the 4 or 8 cell stage. In a tropical climate, the egg will hatch within 24 hours and only L1 larvae will then be detectable.
