I'm trying to supplement Squeek and Lickorish's diet with fish oil or omega fatty acids to combat dander, esp on Lickorish. I bought grizzly salmon oil, offered it alone, no takers. Mixed it with food, they don't want it, even their favorite food went uneaten. also tried a powdered form, NaturVet Ultimate Skin & coat supplement. Squeek ate a little of her food with that mixed in, but Lickorish again wouldn't eat. Lickorish sometimes doesn't eat anyway, but I made sure it was a favorite food. Not sure what to try next, or maybe just give it up. they do have very soft and shiny coats, its just the dander and occasional scratching.
