Yappetizers sardines dog treat is a great source of omega-3 fatty acids, which support the immune system. Sardines may also decrease inflammation and can keep your dog’s coat looking shiny and healthy. Our sardine treat is slowly dehydrated over a long period of time. This slow process of dehydration perfectly preserves our sardine treat without the use of additives or preservatives. Our dehydration process removes almost all of the moisture allowing this treat to be naturally shelf stable for over 2 years. As with all of our products our sardines are human-grade and sourced from federally inspected plants. This salmon treat is hand-made in our very own CFIA (Canadian Food Inspection Agency) certified plant located in Richmond, BC Canada.
