I have two dogs, a terrier mut named Bart, and a Maltese, Buddy. I've had Bart for 8 years, and walk him daily. Bart has always had a very normal stool, and has always been very regular. Buddy has been with us for a year now. I walk them both together, but Buddy has really been a problem. I've had to double the length of my regular walks with Bart, and, still, it is not uncommon for Buddy to have days, sometimes two or three in a row, without a bowel movement. During this time, he usually has bad gas as well. A friend suggested Lax-eze. I mix about a teaspoon into his food each meal, and now Buddy has regular, normal bowel movements and, best of all, no more gas! I'm very happy with the results.
