"Ideally, someone giving advice (as opposed to someone sharing their own personal experiences and opinions) should have a real name and verifiable credentials and not stand as an anonymous person".
Excellent post, thank you. It seems that sometimes, the more experienced but un-credentialed folks (although well meaning) forget that that there is usually more than one way to achieve a goal. They have their ways of caring for and training their GSD's, but their way is only one of many.
I too have been alarmed at some of the "diagnosis" posts. For many GSD owners, vet bills are a consideration and they may be prone to taking advise here and not consulting a Vet as soon as they should. I have also seen posts questioning a Vet's diagnosis, causing un-necessary additional testing and expense to the poster with the problem.
All said, this site is the best resource for basic information on the GSD that I have found. Thanks moderators - for moderating!
