Sure, some of those one-time posters may be jerking our legs. However, I can't say I'd get frustrated or condemn people who turn to PT before they schedule an appointment with their vet. Many times, the "health problem" can easily be abated with time and patience. I think a previous thread explains quite eloquently why people come to PT first:

I can understand your frustration, but some people really don't know when to wait it out and when to visit their vets. The best we can hope for is to educate those who know less and pray they do the right thing.
