Last summer I nursed my two precious old dogs through their last days. Both had been treated for tapeworms in the past. Missy had some "rice" on her rear end, but her heart was failing and I decided not to have her treated when it was evident she was not going to live much longer. I was afraid I had been exposed to any worms they might have had as I had to clean up after them several times a day. (But what else could I do for my two faithful companions and dear friends?)
