chester is a itchy dog, I use salmon oil works well, I have now wash bedding or anything he is in contact with a extra rinse and use free and clear laundry soap and no dryer sheets or anything, no cleaners, no carpet powders and no plug in freshners, and his is envirmential mostly but change of soap will make him itch horribly, and it sounds like it is probably not food, good luck, hopefully maybe a second opinion will help, poor baby it is hard to watch them |
