SAME HERE!!! I chalked it up though to all the "free samples" I've been using as training treats though with Enda. Jinjo I was a bit surprising because his ears seemed to be itchy to him over the last month or two, but only one of his had anything in it and it wasn't much. But that would make sense if it were the food samples as he hasn't been getting much of them. But Enda's ears are back to that dark nasty potting soil looking stuff! She was like that on the Merrick so I stopped that food and changed. She had been fine on the TotW prairie one, but she refused to eat the last Lamb one I bought and after some going through stuff I finally just put her on Raw. Since I've been using the kibbles as training treats this has happened. She is now eating though the TotW, about 1/2 cup at bed time. Sorry, I can't offer help, but now you have made me more curious! I mean I could easily say it was one of the samples as not all of them are the greatest of quality, but I've also been feeding TotW during this time (the Lamb formula)?
