Do you see one or more of these signs in your dog? Then their gut flora could use some extra support:
Give Probiotics daily and support the gut from the inside out.
Probiotics support your dog's gut in three ways at once:
This is how you restore balance from the inside out — for firmer stools, less itching and a nicer coat.
Weeks 1-2
The good bacteria begin to settle in. Some dogs already have firmer stools.

Month 3+
A healthy tummy as the foundation: a glossy coat and a dog who feels good.

Our formula was developed in collaboration with vets and experts and is based on scientific research.
We use spore-forming probiotic strains that survive the stomach and reach the gut alive.
Our chews genuinely help dogs get firmer stools, scratch less and feel better from the inside out, day after day.
Based on scientific research, almost 50% of dogs will deal with digestive or skin problems sooner or later — from soft stools and flatulence to itching and a dull coat. Because 70 to 80% of the immune system sits in the gut, the problem often starts in the tummy — not on the skin. Our probiotic chews contain thoroughly researched strains that restore the gut flora, firm up stools and relieve itching from the inside out.

Dog's age (years)
The risk of gut and skin problems rises the older a dog gets.
The truth: there's a huge difference.
It comes down to the number of strains, the amount of live CFU and whether prebiotics and enzymes are included. Many cheap products contain just one strain and too few live bacteria to make a difference.
Our formula combines 5 strains, 60 billion CFU, plus prebiotics and enzymes — so the good bacteria actually arrive and settle in.
The truth: this doubt is understandable. Many owners have already tried something with no results.
The difference lies in the formulation and dosage. Our formula combines probiotics, prebiotics and enzymes in the right ratio, designed for good absorption.
Many dogs show firmer stools and less scratching within 3 weeks. And if not, you carry no risk thanks to the 60-day money-back guarantee.
My dog no longer bites his skin open — he was itching a lot. His stools look good now too. Works better than the meds from the vet.

My dog refuses to eat the chew. I now mix it into his food, and that works.
I still have to wait and see — he hasn't been taking it for a week yet.
