Your small dog has been getting the wrong formula.
The scratching. The soft stool. The dull coat. The low energy. They look like four different problems. They all trace back to one place — a gut that was never given what a small dog specifically needs.

From the Founder
A promise made to a 10 lb Shih Tzu
Cocoa is my 10 lb Shih Tzu. For over two years I watched him scratch himself raw, clean up soft stool every morning, and sat in vet offices hearing "he's just sensitive." I tried every supplement I could find. Nothing was dosed for a dog his size.
So I built one.
Little Belly is manufactured to pharmaceutical-grade standards in a GMP-certified, NASC member facility with over 60 years of clinical veterinary nutrition experience. I didn't settle for less because Cocoa deserved better. Your dog does too.
That's Little Belly. Made for Cocoa. And now for yours.
We started this for one dog.
Thousands of small dog owners later — our hearts are genuinely full.
