yes we have, this is how we figured out the chicken issue. We had her on a chicken based kibble and she had very, very loose stools. We had planned on raw so we slowly worked into it, I got the percentages to feed from you actually, thanks again. The first few days on raw she did ok with beef, pork, lamb. The stools firmed up and were smaller, more regular poop like. But then we fed chicken and yikes!!!!!! She never has pottied in our bedroom before, this is her room too, and wow, all I can say is she was considerate enough to go to the bathroom and use the tile. It looked like, well, let's just say I have never seen such a mess and immediately felt guilty for feeding her whatever had caused this reaction. I thought maybe she was just having a hard time with the switch. I had bought loads of raw chicken and some beef, pork, and lamb but chicken was going to be a larger percentage due to to affordability. When we fed her beef, it was fine, but chicken reacted violently to her tummy. We went to the duck and potato kibble and saw improvement within 2 days and now she has normal stools, very easy to scooper up. I am disappointed to not be able to feed raw all the time to my girl, but beef/pork/lamb are expensive and she needs so much per day. We are very happy with the Natural Balance kibble, I have used it before with great success- my shi tzu lived 16yrs on it. We just make sure we avoid ALL chicken with her. She still gets some raw with her dinner each day and this seems to work well enough. Mean while, I have become a wiz at roasting whole chickens. LOL Thanks for the advice though, I truly appreciate the help.
