Symptoms In My Dog Are: Scooting On The Ground, Really Bloated, Trouble With Bm’s, And Slight Seizure Like

episodes. any ideas what it is? Please do not say take him to the vet, his appt is tomorrow, i just want to know kind of what to expect. i was told it may be tapeworms, and the seizures are because his blood sugar is too low due to the worms. he had fleas really bad when i bought him, so that kind of fits. what do you think?
