I filed a complaint with Blue Buffalo and how their food was making my Buster very ill. It was affecting his kidneys and he was drinking lots of water and throwing up constantly. I told Buster to the Vet on various occasions and we did blood tests and x-rays. We changed his food to one recommended by our Vet however the damage is done. My babies kidneys have been permanently affected, he is on a kidney special diet. And though he is in recession, he doesn't have more than a year to live. He is only 5 years old. And Blue Buffalo denies their responsibility. We not only loss our beloved companion by also with numerous Vet expenses that they caused. Something should be done about this company. Can we do a class action suit?
