I have noticed little worms on my pets rectum that look like sesame seeds or grains of white rice. What are these?
These are tapeworm segments. Your pet ingested a flea at some point, and that flea carried the tapeworm. Now your pet needs a prescription deworming medication. Call us to see if we can dispense it immediately (if we have examined your pet recently) or if you will need to schedule an exam. You must also treat your pet for fleas to prevent re-infestation.
