Lets see...

The good news is I got a great tip about a very helpful yahoo group dedicated to dogs with orthopedic problems and it is a font of information, the bad news is that Dogger lost the ability to lie down on her own and I couldn't find reference to that anywhere. I also am beginning to think that Dogger isn't putting any weight on her back legs at all and all her weight is being carried by her front legs. I'm calling her doctor first thing. Oh? and the back leg weakness? could also be her Addison's flaring.
