Is Endurosyn® right for my pet?

A normal GI system has a healthy balance of microorganisms, but your dog’s or cat’s system can be disrupted by: 

  • Dietary changes or indiscretions 
  • Stress from boarding, travel or hospitalization 
  • Antibiotic therapy 
  • Deworming 

You can give your pet Endurosyn® before or during stressful situations or after antibiotic therapy, deworming or digestive upset.
