One Chew. Every Day.

Hard-working dogs put their gut through a lot. Long training days, high-protein diets, and physical stress all disrupt the microbiome. Luno's triple-action formula helps support healthy digestion so what goes in comes out clean, firm, and consistent — every day.

Excess gas is one of the first signs of an imbalanced gut. Probiotics help restore the bacterial balance that gets knocked off by exercise, stress, and diet. Less bloating, less odor, less mess — so your dog is comfortable after the work is done.

A healthy gut lining absorbs more from every meal. If your dog's microbiome is off, even the best food gets wasted. Luno helps maintain the gut environment where nutrients are actually absorbed — so more of what you feed becomes usable fuel.

Most of a dog's immune system lives in the gut. A balanced microbiome means a stronger baseline defense — not just against illness but against the everyday wear that hard-working dogs face. Support the gut, support everything else.

Switching foods is one of the most common triggers for digestive upset in dogs. Luno helps maintain gut stability during transitions — less loose stool, less gas, and a faster adjustment period when you change what your dog eats.

Travel stress is a real gut disruptor. Changes in routine, unfamiliar environments, and car rides all spike cortisol — which hits the gut fast. A balanced microbiome helps your dog stay steady when their environment isn't.

Working and sporting dogs have different nutritional demands than the average pet. Their gut takes more stress, processes more protein, and needs more support. Luno is built for that load — not for the couch dog who goes on one walk a day.

Prebiotics feed the good bacteria. Probiotics seed and maintain it. Postbiotics complete the cycle. Most products only do one. Luno does all three — so your dog's microbiome gets full support from every angle.

When the gut is off, energy takes the hit. Poor absorption means less fuel getting to the muscles that need it. A healthy gut means more of every meal gets converted into actual output — so your dog shows up ready, not sluggish.

Gut health is performance health. When digestion is working right, everything else runs smoother — energy, immunity, coat condition, mood. Luno gives your dog the gut foundation to train harder, recover cleaner, and go again tomorrow.
