The Noisy Engine
Have you ever gone to the mechanic with your car due to a strange noise in the engine? When the mechanic looked at your car, did they test it with various diagnostics to find the cause of the noise or did they just say "mmmm looks like noisy engine lets spray some WD 40 on it and come back if it is still noisy", probably not.
Well so often the symptoms ie. "noisy engine" are treated with no regard for the cause. I cannot tell you how often in the past 30 years I have seen this occur. Just the other day I saw a dog who was getting Rimadyl for "noisy engine", lol actually lameness that was not caused by a disease process. It turned out that this dog has subluxations within the lumbar along with psoas and assorted muscle strain. Adjusting the dog and doing exercises has dramatically improved him.
Please remember not to treat the " noisy engine " when the cause is not showing up on standard vet testing and consider the concept of subluxation complex, you will help lots of animals!
