Geez, I would think he would be worm free by then, when I got Sox as a pup, she was so full of worms she was round with them and it only took her about 3 days
to get rid of them.
I thought he would be (but I've been lucky enough to never have a dog with worms before)...anyway, I just picked up a pile and I didn't see any, so I think we are getting near the end!
