Many cats and dogs are prone to sensitive digestive systems and as a result, experience symptoms that can be uncomfortable to pets and their owners. Difficulties with digestion can lead to upset stomach, gas, diarrhea, and loss of appetite as well as worried, frustrated owners. That’s when digestive support and enzyme medications can help. These products are designed to ease digestive distress by promoting digestion and easing symptoms, thanks to enzymes, probiotics, and prebiotics that help break down food and improve absorption. In addition, they also promote the growth of “good” bacteria that can eliminate gas and make stools firmer when taken on a regular basis. Digestive support supplements may also inhibit the growth of yeast and reduce inflammation.
