YOUR PURCHASE HELPS A DOG RESCUE: For every bottle sold, we donate a bottle to a dog rescue. A major expense of dog rescues is dog food. Because rescues are run on limited funds, they don't always have the ability to buy the best dog food. As we know, nutrition is a very important part when rescuing a malnourished dog. By donating our salmon oil we can help rescues supplement their food and improve the health of their rescued friends.

DOG RESCUES: Each month we donate to different rescues throughout the USA. At the end of every month, we tally up the number of products sold. Based on the number, we determine how many rescues we can donate to for that month. We donate down our list of rescues until each one has received a donation and then we go back to the top of our list.
