QUESTION
Anal pruritis in dogs is associated with?
OPTIONS
(A) Dipylidium caninum
(B) Toxocara canis
(C) Ancylostoma caninum
(D) Diphyllobothrium latum
ANSWER
(A) Dipylidium caninum
EXPLANATION
Dipylidium caninum commonly causes anal pruritus in dogs because motile gravid proglottids may emerge from the anus and irritate the perianal skin. Toxocara and Ancylostoma can cause gastrointestinal disease but are not classically associated with the characteristic “scooting” from tapeworm segments, and Diphyllobothrium is not the usual canine cause.
