British animal-free pet food brand The Pack and German biotech start-up MicroHarvest have launched Gut Bites, a microbial protein dog treat for the UK market.

The plant-based and oven-baked treats feature MicroHarvest’s proprietary microbial protein ingredient, and are formulated to be a gut-friendly and allergy-friendly alternative to conventional meat-based treats.

Damien Clarkson, MD of Prefera Pet Food UK which operates The Pack, said: “Our community of dog owners often tells us they struggle with picky eaters and pets with allergies. Gut Bites is our answer, a delicious, functional treat that’s also allergy-friendly. MicroHarvest’s microbial protein stood out as a game-changer, helping us deliver something innovative, healthy, and sustainable.” 

Katelijne Bekers, CEO of MicroHarvest, added: “Entering the UK, where 36% of households own a dog, is a major step for us. This collaboration shows microbial protein isn’t just a sustainable solution; dogs truly enjoy it. Gut Bites proves that health, taste, and environmental responsibility can go hand in hand.”

Since the manufacture of pet food is thought to produce 106 million tonnes of CO₂ a year, MicroHarvest’s protein provides an alternative that reduces the environmental impact by more than 90% when compared to beef and doesn’t require any farms, fertiliser, or pesticides.
