As with so many other things, cancer also affects levels of certain amino acids in the blood, which can lead to further health problems.  Because of this, supplementing your dog’s diet with the amino acids Arginine and Glutamine can be helpful.  Arginine helps to reduce tumor growth and metastasis, and Glutamine helps to prevent wasting and can also help to prevent some of the common gastrointestinal side effects of chemotherapy.  You may find that some recommended cancer-supplements already contain one or both of these amino acids, so always read the labels. 

Please Note:  Do not give your dog a Glutamine supplement if they have epilepsy or are on anti-seizure medication.
