One should definitely try this product before succumbing to the usual antibiotic treatment advice from your average vet. Also, very few antibiotics can affect nosal passages, so if you do get an antibiotic from your vet, make sure it is not a waste in that respect.
Our little dog has had severe allergies with sneezing and a runny nose for two years. The vets had no solution as it did not respond to steroids or antibiotics. We tried this and within a very short time the continually runny nose and sneezing was down to a manageable 2-3 times a day. After using for several months, we decided to try to not use it and see if it made a difference. Within 2 days, our little fellow's nose was running ALL the time again. Needless to say, we restarted it and will continue to use it.
I honestly did not believe this would work. My sister bought it for my cat but I didn't understand how it could possible treat her symptoms. Surprisingly, it works very well, better than most medications, and it caused no side effects.
