Just a heads up on the Wheat Germ Oil, It is a great source of Omega 6 but if it outweighs your dogs Omega 3 intake it could be hazardous to their health. I believe the ratio is something like 10(6) to 1(3) has shown to cause problems.
I read that also. I never did find a ratio that everyone agreed on as safe.
"n−3 and n−6 compete for the same metabolic enzymes, thus the n−6:n−3 ratio will significantly influence the ratio of the ensuing eicosanoids (hormones), (e.g. prostaglandins, leukotrienes, thromboxanes etc.), and will alter the body's metabolic function."
I have been giving my dogs fish oil capsules periodically for a long time. I think that if I give those in conjunction with the wheat germ oil, the ratio won't be too skewed.
