Our dog has begun eating dandelions on his walks with my husband, so much so that my husband has complained it has really added to the time it takes to get through their regular route.
We checked with our vet to be sure dandelions aren't toxic and she said no, they aren't, and can actually be beneficial. I did some research and found that dandelions can help with an assortment of ailments such as allergies, arthritis, constipation, diabetes, diuretic, kidney disease, liver disease, mild pain and urinary disorders. They contain vitamins A, B, C, and E, plus potassium, calcium, and iron to act as a tonic for the urinary system and liver.
Since Mickey is on PhenoBarbitol for seizures, a medication that can cause liver problems, I see this as a unique way of possibly staving off those problems. (One caution: if you allow your dog to eat dandelions be sure they are chemical free--no pesticides--and be aware they are a diuretic. Lots of potty breaks will be needed! Also, dandelions aren't recommended for dogs or cats with bile duct or gallbladder disorders.)
Maybe Mickey's really smart and a naturopath at heart. Or maybe he just likes dandelions. Either way, our yard will be weed-free this summer.
