My dog has a breed-related respiratory issue; now at 14 years old, this is a major concern for her health. We had resigned ourselves to the vets’ prognosis that we should be appreciative of having her in our lives as long as we had, though I was unsatisfied with this outcome. We began by administering 4 drops of chlorine dioxide in her water and saw an incredible improvement! Now I have reduced it to 2 drops since she no longer seems to struggle for breath, and it looks like she will make it through her twilight years without any breathing problems.
