Tapeworms (Dipylidium caninum, Taenia spp.)

Why they matter: Common and often noticed as “rice-like” segments near the rear end or in stool.

How dogs get them:

Common signs: Usually mild; scooting, itchy rear, visible segments.

Diagnosis: Often based on seeing segments; fecal tests may miss them.

Treatment & prevention: A specific dewormer is needed, plus flea control (otherwise they come right back).
