Unlike many of their fishy counterparts, Sardines are ALWAYS caught rather than farmed. That means that they are more likely to be free of all those antibiotics, growth hormones and other nasty drugs. Furthermore, they are usually caught YOUNG, and so have not accrued high levels of heavy metals or other toxins like their larger brethren.
Sardines are an excellent treat for your dog because they are super-rich in those essential omega fatty acids. They are also rich in calcium (the bones are fine and soft and safe to eat), and vitamin D.
