My dog is passing worms and his ribcage area is swollen. What could this be?

Answer

The swelling may or may not be due to the worm burden. If you saw segments they are tapeworms, if you saw long worms they are probably roundworms. You need to check if the swelling is all over or only in one spot and if it is over the stomach. You most likely need to take him to your local vet as soon as possible.
