I have a three year old Viszla “Yaeger” that has allergic bronchitis. He has been on Chinese herbs and acupuncture treatments with success for the last year. His coughing has improved 90% with these treatments, but he still honks when he gets excited. After the addition of Fido-Vite to his diet for the last month I noticed further improvement in his coughing episodes. He only coughs 5% of the time anymore. I attribute the probiotics and additional vitamins to his diet to strenghthening his immune system and improve the immune fighting qualities of his intestinal tract. Thanks Fido-Vite for helping me treat my dog with natural products instead of medications.
