Kirkland Pet Foods


Consumer Complaints & Reviews


I currently have 7 dogs, all rescues. I have been feeding Kirkland Lamb & Rice to my dogs for over 6 years. My dogs have always thrived. In November I noticed my 5 year old Aussie/Border Collie cross, Keno, started leaking urine. As a former vet tech, I know that a male dog should NEVER leak urine.

I immediately took him to the vet and his urine was full of crystals and he had a urinary tract infection with a PH of 8.5 (PH of dog urine should be 6), Keno also had to have x-rays to make sure the high PH levels hadn't caused bladder stones to form, which can be life threatening. My vet immediately said it was food related. I had my 1 year old Border Collie that I had rescued a few months ago (Penny) tested because she started having 'accidents'....her PH was 7.5 and she also had a urinary tract infection.

I decided to test a third dog, my 1 year old German Shepherd cross, Gibson, and his PH level was also high. Having 3 of my dogs test with high PH levels was enough for me to know something has definitely changed in the Kirkland food, and it wasn't just one dog suddenly having problems.

I spent about $200 in vet bills and will never again use Kirkland foods (I used to feed it to my cats as well), and have told other people that there is a problem and they need to get their dogs off Kirkland foods. My dogs are now on Foster & Smith Chicken and Brown Rice and all their PH levels have returned to normal and they are healthy again. I contacted Costco and they told me that Diamond Pet Foods made their Kirkland dog foods. I left numerous messages at Diamond Pet Foods but no one returned my calls. You would think a company would care that their food was responsible for making animals sick.


I fed my dog Kirkland brand food from costco...He became very sick.. Also 2 of our cats passed away, that were also eating the food..

My dog could have died, along with the thousands of other animals that ate this tainted food... I lost two cats. I am devastated that my animals had to go through this..We shouldnt have to fear that the food that we are feeding our pets could actually poison them.
