Natural Remedies to Treat Kennel Cough in Dogs

My Pomeranian, Holly, had kennel cough. WE used the 3% Hydrogen Peroxide, but the cough would just get weaker. We then tried no-dye Benadryl in the the morning and at night. It works great she has a lot of energy during the day and at night she can sleep. We are going to do this remedy for another week so she can get better.
