Sorry if I left this impression...NO! Tummy growls happen for many reasons...some of it is just the natural part of digestion as food is making its way through the pipes. It often accompanies eating something that's not agreeing with you...gas...or an intestinal bug that results in diarrhea. I just happened to stumble on the Tapeworm egg sac description when I was trying to figure out why my pups tummy is gurgling so much. Knowing Sugar...she probably wolfed down some tastey morsel on the ground when I wasn't looking...she's fast as lightening!
