HI Pamela, I have a similar problem with my foster boxer here - have a look at this post -
Very smelly wind... - I have been using enzymes and probiotics for nearly 2 months now and I am delighted to say that the wind has all but stopped - thank goodness - it was absolutely horrendous. His poops are still on the loose side but I would say they are a good 40 percent better than when we first got him. I still think his diet needs some adjusting so am I trying different foods to see if I can find one that suits him as unfortunately I can't fed him raw - which is my preferred choice.
