After you get the pill from the vet for tapeworms, and administer it....are you suppose to see more of the dead tapeworms in the stool?.....I've been inspecting every single poop that she has made from the day I brought her home and I haven't seen a trace of any......but last night...I saw a piece of a live tapeworm in her stool...so this morning I called the vet and went to pick up 1/4 of a pill (hehe)...anyway...I gave it to her as soon as I got it home...now she has pooped twice, and twice I've seen a good amount of tapeworms in the poop....is this how it suppose to work?...that quickly?...and for how long?......Thanks
