If your dog has a dry wet cough, the natural Pets C&C (formerly Vintesta) may work better. If your dog has the canine influenza virus (canine flu), we recommend giving both the natural organic herbal Vintesta (formerly Pet's Cough & Cold Formula) AND Tossa-K (formerly Kennel-Koff) remedies. The Vintesta (formerly Pet's Cough & Cold Formula) soothes the throat and cough (like Formula 44D or Robitussin for people) and the Tossa-K is a natural antibiotic to fight the upper respiratory bacterial infection.
