Kenzie, on the first day in our home, started coughing, and showing signs of getting Kennel Caugh. I straight away put her on echinacea (1cc, 2 times a day). She kept coughing/wheezing for a couple more days, but now she has been caugh free for three days! Kenzie has also started itching quite a bit on her back/rump, and I have found quite a few scabs under her collar. I am going to try bathing her in the oatmeal, tea tree oil, papaya oil and aloe vera. A good webpage about natural itch relef is  http://www.stopdogitching.com/natural-remedies-stop-dog-itching.html. I will she how she is in a few days, and then try an Apple Cider Vinegar rinse.
