Absolutely not, at Big Dog, when we say 100% natural we mean 100% natural. This means no added preservatives, no modern preservation methods like irradiation which impact the nutritional quality of the food nor do we add any synthetic additives such as vitamins and minerals, colours or flavours.
Our preservation method for our food is freezing and once our product has been thawed ready to serve to your pet, it will last up to 3 days when kept in the fridge.
Whilst our food may last longer than 3 days, be sure to keep an eye out for signs of deterioration of the product like ballooning of the packaging. If this occurs, do not serve your pet and dispose of the product.
