More Complaints About Blue Buffalo Pet Food

January 2, 2014

Not long ago, I wrote an article about consumers who had reported negative experiences with Blue Buffalo Pet Food.  I found quite a bit of documented incidents on the Internet detailing dogs and cats that became ill after eating various Blue Buffalo products.

A team of researchers from Michigan State University conducted a study in 2010 and found a link between a group of dogs tested that had eaten a diet of Blue Buffalo’s Wilderness Chicken Recipe and elevated levels of calcium in their blood (

All the dogs tested were found to have extremely high levels of Vitamin D.  The dogs came from 8 states and consisted of both purebred and mixed breeds.

When their diets were changed, the dogs test recovered.

This is not a new report, since the study was conducted in 2010.  But the many reports by consumers about their pets experiencing illness after eating the products occurred in 2013.  As late as December 28, one pet owner wrote that she switched her dogs to a Blue Buffalo product in September, 2013, because they were experiencing allergic skin reactions.  Within two days, both dogs were “drinking and urinating like crazy.”  She and her vet found that the symptoms were just like those shown in the Michigan State report of 2010.

You can read these complaints on the Consumer Affairs website by clicking this link.

My pets don’t eat this brand of food, so I can’t personally comment on it.  However,  if I were feeding it to my dogs or cats, I would keep a very close eye out for signs of trouble.  When complaints continue to surface, it makes me nervous.

A reader named Laura sent me the following: ” I’ve posted this elsewhere but I’d like the information to get to more people. If your pet is having (sometimes bloody) diarrhea, vomiting, weight loss, smelly poop, dehydration, urinary difficulty or other symptoms PLEASE call Blue Buffalo with the batch information on the food bag so they can get to the bottom of what is making them sick. Call them! They had this to say about my complaint. “However if you feel that your pet is exhibiting any complications as a result of a BLUE product please contact us (after contacting your vet first of course) to discuss. We will do everything we can to help and to get to the bottom of it: (800) 919-2833.” I have called them and the pet store where we bought the food. We already threw our cat food bag away, it was the blue one, so I didn’t have the batch number or anything to give them to help fix this. I have 4 cats ranging in age of 7 years to 9 months, 2 male, 2 female and they all are sick with the symptoms I described above. When you call also ask for a form to try to get your vet bills paid for by the company, after of course their lawyers and vets go over it… PLEASE pass this info on to others that may have the information the company needs. And call the store you bought the food at if your pet is having these problems.”

If you are feeding Blue Buffalo to your pet, be sure to watch him or her carefully.
