And, it's tapeworms.
Of all the worms to get, tapeworms is actually the best to get. Apparently. It's still disgusting if you ask me.
Our vet called me back yesterday to inform me of the news. As it turns out, tapeworms are much easier to treat (one single pill vs. weeks of treatment!) and kill off completely than the horrible roundworms that we were afraid the dogs may be infected with.
So, I gave both dogs a pill last night to kill off the tapeworms and then topped it off with a good flea treatment (dogs, and cats, tend to get tapeworms from eating an infected/carrying flea). I've treated two of the three cats with the flea medication, and will try to tackle Twyla sometime tomorrow, now that Jon is back home (yay!) to help me out. We'll also give the cats their tapeworm meds tomorrow too (theirs is a topical, rather than a pill, so I can't do the flea and tapeworm treatment on the same night).
We've washed all the bedding in the house and will be vacuuming the rugs and giving the dogs big baths just to be sure. But otherwise, another crisis deftly averted! WHEW.
