Sardines

100% Sardines.
 
These tasty, somewhat stinky, little fish are a great source of protein, omega 3s, Vitamin B12, Vitamin D, calcium and selenium. 
 
Sardines can be a great choice for dogs with arthritis or joint issues. 
 
Vitamin B12 is important for nerve and brain function, while calcium not only helps keep bones and teeth strong and healthy it also helps with muscle building and function and keeping the heart strong. 
Selenium is a vital mineral with a long list of health benefits from its antioxidant and anti-cancer properties to improved joint health, cardiovascular disease prevention, pancreatic function and strengthening the immune system.
