Here's one report from the Whole Dog Journal:
By Mary Straus
Fish oil is probably the most important supplement you can add to your dog’s diet, regardless of what type of diet you feed. EPA and DHA, the omega-3 fatty acids in fish oil, provide widespread benefits, but they are fragile and unlikely to survive storage in bags of kibble, or may be rancid even before being added to pet foods. Krill oil and whole fish also provide EPA and DHA that may be better absorbed, providing similar benefits in smaller doses.
BENEFITS: Proven benefits from EPA and DHA include:
-Improving the coat and skin.
-Reducing inflammation due to conditions such as arthritis, allergies, and inflammatory bowel disease.
-Regulating the immune system, boosting those that are suppressed and calming overactive immune systems for dogs with allergies or autoimmune diseases.
-Aiding in mental development of fetuses and puppies, and improving cognitive function in older dogs.
-Lowering blood pressure and triglycerides.
-Providing support for dogs with kidney disease, heart disease, and cancer.
-Promoting weight loss in overweight dogs.
You be the judge and if others are using it, I would like hear your thoughts. I'm going to continue with it everyday.
