I want to make it official. Dolly definitely has learned "poop on demand". We do it once a day (at present) right before I take her up to bed. I hold her around the chest so her tail is hanging down, and place 2 fingers on either side of her rectum but do not pinch, my fingers are just there. I don't know if it helps her focus...? Anyway, then she goes and she may go again.
I adopted Dolly March 7 of last year. She was 7 months old and had been injured at 2 months, which would have been around October 2008. So it has been about 17 months since her injury and we have just learned "poop on demand" without pinching, and we saw the first signs of the ability at about 14 months. She does not seem to have a strong ability to move her bowels right now, when I compare her to Katie who was paralyzed 6 years ago and can really exert. I hope it will continue to get better as time goes on. This may be useful to someone else dealing with a dog with incontinence due to an injury in the tail area.
I am very
proud of her. We are very happy.
I remember reading that Dolcezza had regained bowel control, now I am so happy to report Dolly has, too.
[EDIT: This only works if the stools are lined up the right way, not every time.]
