Excellent product. Has given my Australian Shepherd relief from a distressing cough due to heart and lung disease.

If you miss the subtle initial symptoms of bronchitis at onset, eg a very mild clearling of the throat it can become quite pernicious with the infection lasting two weeks and recovery taking considerably longer than this if treated with antibiotics. This was the second bout of canine bronchitis I had experienced and, unfortunately, I missed the onset and was not able to obtain RespraEze and the High Potency vitamin C in the short term, so the infection once again became severe. This time no antibiotics were used and after the two weeks of infection, recovery was reduced to two weeks. It's good to know I can rely on this formula to complete recovery from severe bronchitis in two weeks rather than administering strong antibiotics endlessly for weeks and recovery taking forever with no discernable incremental results. My recommendation is to become very aware that unusual throat clearing over 1 or 2 days is likely to become bronchitis and act with both of these products to stop the infection before it gets out of hand.
