I use both Mercola digestive enzymes and Mercola Complete Probiotics. They are well worth the money. My dogs are doing so well. Cost wise I guess it the size of your dog or dogs would come in to play as to how long they last. My dogs are 5 lbs., 6 lbs., & 7.3 lb.s. When I purchase them I always go for their deals where you can buy more than one at a time and get a “little” bit of a break in cost.
