All 6 dogs on the 2 properties got kennel cough (dog colds) at the same time. The 3 next door got "a deal" from the vet because of 3 at once and were only charged $65.00. The 2 on my side I treated with a clove of garlice (put down their throat with a finger) and a 1/2 dropperful of Echinacea for 3 days and then just the garlic for another 7 days. All doctors have you take your meds for 10 days so as not to grow a superbug. Use garlic as an antibiotic/antiviral and treat it as such. It works. And tea tree oil is the best infection fighter for anyone, anything I've put it on. Real easy to apply in an open animal would with a dropper. Ellen A.
