The kind that can clear a room. Joking aside, this can be a serious situation. Farts occur when gas builds up in your dog’s intestinal tract and colon. Your Woof passing gas now and then should be nothing to worry about. However, if it is a common occurrence, your Woof could have a food intolerance or a digestive issue. It is time to review our ‘allergy’ section and make some food changes. Simple gas build-up can be lessened considerably with probiotics, enzymes added to the dog food, and the use of some highly effective no-gas supplements we recommend.
