What a beauty Toby is! Thanks for sharing the pics! The first GSD i lived with looked an awful lot like Toby. She was such a sweetheart too and turned me into a Shepherd fan. 

 I'd like to stress something jerry said. We also keep our three tripawd GSDs really lean. It is one of the most important things we can do for them, especially since they are prone to hip problems. Case in point is Austin who came to us severely underweight and in poor condition. We fed him up because we wanted him to gain weight and he went from about 60 pounds to 80 pounds, about right for a dog his size. With 4 legs. We were so proud of ourselves and then we realized he was having real trouble getting around. Not as bad as Toby was but his mobility really declined. We realized he just couldnt carry that extra weight. Now we keep him between 70 and 72 pounds and as he lost the weight he regained his mobility. 

So that was a long story but the point is no matter what else might be going on with Toby, if she is carrying any extra weight it wont help and in fact, it could be a contributing factor as we saw with Austin. Its hard to tell from her pictures if she is overweight because you can see she has a really thick coat (and what an amazing tail!) but you might want to talk to your vet and ask what he thinks a reasonable weight would be for Toby at this point and then put her on a diet if needed. 

Sorry, I'll get off my soapbox now! Looking forward to more pictures and hearing what happens at the vet tomorrow. We'll be thinking of you.
