Sardines - Can they replace some supplements during certain periods?

Hello, If you regularly add sardines to your dog's food, either raw or lightly heat-treated, could this replace some supplements? Or not at all? 😄

• Hello! 😊 Sardines can replace omega-3 supplements (fish oil), but unfortunately not other supplements. They mainly contribute fat (EPA/DHA) and protein, while other supplements add specific vitamins, minerals and trace elements that are not covered in sufficient quantities by sardines alone. 🐟 Since sardines contain a lot of omega-3 (PUFA), the need for antioxidants also increases – especially vitamin E, which protects the fat from degradation in the body. That’s why recipes calling for fish or sardines often include a bit more wheat germ oil (a source of vitamin E) to keep everything in balance.
• OK, thank you 😀
