Blue Buffalo and Petco have raised more than US$2.4 million in 2014 for pet cancer research. The partnership, which began in 2010, has raised more than US$7 million total so far. This year, Blue Buffalo donated US$1 to go to pet cancer research for every bag of Blue dog or cat food sold during the month of May at any of the more than 1,300 Petcos nationwide. Additionally, Petco customers were asked to make a donation at the cash register or online.

Money raised will fund efforts like the Denver, Colorado-based Morris Animal Foundation’s 5-5-5 Initiative, which will conduct five annual clinical trials on osteosarcoma, the most common form of bone cancer in dogs. Additional money will be distributed to universities and clinics across the US that are conducting research on the causes, prevention and treatment of canine and feline cancer, as well as to organizations that are dedicated to helping families in need cover the cost of pet cancer treatments.
