I have a 9 yr old dog with middle/late stage congestive heart failure. She’s on a cocktail of Pimobendan, Furosemide, and Spironlactone for the condition. But she also gets crazy car sick in general, vomiting many times per trip. Has done so since she was a pup. Anyone have any experience with OTC meds like Dramamine or natural/organic solutions in dogs with a similar condition?
