The inability to properly digest food due to the lack of natural digestive enzymes produced by the pancreas is found frequently in some breeds of dogs. Supplemental enzyme therapy, in the form of whole live pancreas derivatives, has been shown to be the best course of action for animals that cannot digest their food thoroughly due to pancreatic enzyme deficiency. However, due to the overall poor absorption of essential nutrients and vitamins that inherently goes with this deficiency, blood levels of vitamin B-12 may also be low. The addition of Vitamin B-12, with intrinsic factor present, will help with this condition. Thomas Laboratories has also added Probiotics (lactobacillus) to this stabilizing formula to promote a healthy, stable bacteria level in the digestive tract, helping to reduce stomach upset and loose stool.
