My dog is a fussy eater, so the Tylan-containing products (Angel's Eyes™/Angel's Glow™) which have a medicinal taste didn't go over well; she'd pretty much rather starve. She will actually eat the I-Stain, and with the I-Stain she tears much less, and the minimal deposits she does get remove easily with tear-free dog shampoo, no harsh chemicals required."
