British pet food brand THE PACK and German biotechnology startup MicroHarvest have introduced Gut Bites, the first microbial protein dog treats in the UK. These treats are created by fermenting agricultural side-streams, reducing the need for additional farmland, pesticides, and fertilizers. The companies claim that this method significantly lowers the product's carbon footprint compared to beef and other plant proteins.

According to research, the pet food industry uses a large amount of land and generates a substantial amount of CO2 emissions, contributing to the environmental impact of meat production. Gut Bites offer a sustainable alternative that is allergen-friendly and suitable for pets with sensitivities and intolerances. Consumer studies have shown a high level of interest in microbial protein dog treats, with palatability tests revealing that even selective small dogs preferred food made with MicroHarvest protein. The launch of Gut Bites demonstrates a commitment to offering innovative, healthy, and sustainable pet products.
