Pets that may benefit from adding either probiotics and/or digestive enzymes to their diet can have symptoms like:
Probiotics are a group of healthy bacteria that should be at 4-6 billion live cultures to be effective and should come from a non-dairy source like plants; but can also come in vegan varieties as well. They can be added to your pet's diet as a supplement of beneficial bacteria in powder, capsule or liquid form. Probiotics help to balance out the stomach flora which allows the stomach to function normally. By incorporating probiotics into your pet's diet, they can also help to keep the walls of the stomach from being irritated after breaking down kibble.
Digestive Enzymes aid in digestive support. They assist in breaking down and digesting foods to make it easier on the animal to assimilate carbohydrates, starches, and grains which are often found in kibble. Also, by adding the digestive enzymes, there is less poop as more is broken down and not passed as stool.
