When stresses occur, such as illness, antibiotic therapy, traveling, kenneling and dietary changes the balance of intestinal microflora is disrupted in your pet’s intestines. Your pet could show signs of illness including diarrhea, decreased appetite and vomiting. They can also be given during and after antibiotic therapy and before stressful conditions such as traveling and kenneling to help support intestinal health. Proviable-DC capsules contain seven strains of probiotic microorganisms with two prebiotics. Dosage: Cats and dogs (all sizes): Give 1 capsule daily or as directed by your veterinarian. Capsules are individually foil packed for freshness.
