Last year, when my dog Roxie was diagnosed with cancer, I immediately came home and spent hours and hours researching things that would help get her better. A lot of the supplements I read about that were recommended, I’d never heard of. There was one that caught my attention though, because of how it is administered in dire cases and what ailments it can help with in both cats and dogs. It was vitamin C. I never realized how many things vitamin C was good for treating in cats and dogs until I researched further.
