stool question

Thanks for the help guys, amokabs he's got the exact symptoms your describing, but he's well out of puppy stage, iv got my dogs on concrete, so it is very noticeable as to what's going on. He has yet to have solid stool in a week or so. Iv wormed the fire out of him with a triple wormer I picked up at the vet supply, how long does an over thee counter take to knock out intestinal worms? And how often do you worm your dogs for intestinal? Iv allways give all my dogs ivomec once a month 1/10 cc per 10lbs. Hog dog or yard dog that's what they get. Never had worms come on me like this.
