For dogs with sensitive stomachs
A calm gut, a happier dog
Tesswyn is a 3-in-1 probiotic and multivitamin chew built for the dogs whose tummies fall apart at the slightest stress.
The problem
You know that look
Most dogs with sensitive stomachs aren't sick. They're stressed. Thunder, the groomer, a new house, even a busier week with the family, and their gut is the first thing to fall apart.
Tesswyn was built for those dogs, and for the people who watch them and want to do something that actually helps.
The product
One soft chew, three jobs done right
- 01A three-strain probiotic blend chosen for what it actually does in a dog's gut: firmer stools, less gas, fewer flare-ups.
- 02Pumpkin and salmon oil to soothe the gut wall and feed the microbiome at the same time.
- 03A daily multivitamin so the rest of your dog—coat, skin, joints, energy—gets quietly looked after too.
What changes
Stop bracing for the bad days
Most dog parents tell us the same thing: the stress days stop being stomach days. The car ride, the storm, the visitor at the door, the stay at the kennel. The trigger still happens. The mess doesn't.
