Raw sardines are highly nutritious for pets, providing a wealth of benefits. Sardines are an excellent source of omega-3 fatty acids. These fatty acids promote healthy skin, coat, and immune function. Sardines also contain essential vitamins and minerals, including vitamin D, vitamin B12, selenium, and calcium. The inclusion of raw sardines in a pet's diet can contribute to overall health, providing essential nutrients, protein, and omega-3 fatty acids that support their well-being. Sardines are also lower in pollutants, toxins and heavy metals as they are lower in the food chain and do not consume other marine species that contain mercury.
