How To Make Your Dog to Poop.
Sometimes it's absolutely necessary to have sample of poop. There are a couple tricks you may make your dog to defecate for you.
*Take one or two paper matches and wet the sulfur tips by putting them into water, or your mouth. Straddle your dog facing its butt. Pull the tail out of the way (if there is any tail) and insert the wet sulfur tips of the matches in your dog’s anus deep enough that just the ends of the matches are visible and hang out just a tiny bit. Release the dog. Usually the dog will start squatting almost immediately to expel the matches. If the dog doesn’t, then you can repeat the steps above. Do not insert more than 4 matches at a time. Rarely do you need to use 4 matches. When the dog squats to expel the matches, it will usually poop too.
*Also, small piece of soap, approximately ½ to 1 inch long and ¾ of inch wide will do the same trick. Cut thin piece of hard hand soap, be sure it has round edges, make it a little bit moister and insert into your dog butt. Soap is natural irritator will cause your dog poop almost immediately. Collect the poop and clean "leftovers".
