This last week, I learned about a disease that is mostly limited to German Shepherds. It's called Degenerative Myelopathy and is an auto-immune disease of the spinal cord. It's a doggie version of Multiple Sclerosis and causes the dog to lose control of its hind legs. It's not painful, but ends up crippling the dog and, as a side effect in the late term, causes incontinence (both types). There are a lot of resources and information about this if you Google the term, the best of which seem to come from the U. of Florida by a vet/Ph.D. named Dr. R. M. Clemmons. Unfortunately, I learned of this disease the hard way and there is no cure for it. I thought my dog was simply getting arthritis because her symptoms started with a limp. During the last couple months, her rear legs would go out from under her when doing one of her famous high-speed, chasing-the-Kong turns. Now she can't jump up into my truck anymore and is losing muscle mass in her haunches, and walks funny much of the time. As a side note, her hips are great, not a trace of displasia at age 9. Anyway, I posted this for informational purposes because I know a great many of us are dog lovers. I hope no one else's dog gets this awful disease.
