I tried to find an article my holistic vet wrote to find what helps explain your dogs specific symptoms.
In TCM, the eyes are related to the liver, the ears - kidneys. I would think that your dog's immune system is struggling from toxic load. The liver is the largest detoxifing organ in the body, and when it cannot process toxins as fast as they come in then the kidneys are left filtering the fallout. These toxins are circulating in the blood and the immune system may have been supressed by vaccines, enviroment, heavy metals (water, vaccines) as well as pesticides (lawn, spot on fleas/tick/heartworm prevention), foods (kibbles that contain GMO's, 4D meats, carbs, and rendered fats - once bag is opened, these fats start to oxidize and become carcinogenic, as well as synthetic vitamins from china)
The good news is that this is an early warning sign of imbalance, detoxing the liver and flushing the kidneys as well as a natural diet with live enzymes and amino acids will help the body help it self.
Dandelion is a mild diuretic and will assist the kidneys in flushing out toxins as well as bad bacteria that can lead to bladder and UTI's and assists in repair of the liver.
Milk Thistle will repair damaged cells of the liver.
However - this won't work well (will help a bit) if adjustments are not made to the above noted.
Note: Once cells in kidneys are damaged, they cannot be repaired. Further assault without prevention will lead to a whole host of other problems as the kidneys work in tandom with the pancreas re: insulin regulation.
EAR INFECTION If the right ear is often infected , the right ear signifies the immune system. The left ear signifies the liver. The left ear is often periodic, spring and fall. The right ear will often flare up during the change of seasons, especially from winter to early summer when the temperature suddenly goes from -25 degrees to 40 degrees above F. That's very hard on the immune system. The Chinese herb for that is astragalus, which is a pretty safe herb. I quite often use bee propolis or goldensea
l to kill bugs in the ear. If it's only one ear, it's an organ system that's involved.
