I have to agree with Lorraine.
I went to 2 Vets and 2 Ortho Specialists, all 4 of them could tell just by a quick examination that indeed Roxy and TJ both have LP. The General Vets would not guess at what Grade they were, they told me the Specialist would be the one to answer that.
The 2 Specialists told me Grade 3 for Roxy. She would carry her leg all the time and she did the 'skip' walk (which I used to think was the "Roxy" walk and I thought it was so cute) - Now, I know better - it was her LP.
Anyway, we didn't bother with x-ray - until the morning of the surgery, the Ortho Dr. wanted to take a quick look at some x-rays just to see, but they can't really know for sure what's going on in there until they are in there.
After Roxy's surgery, the Ortho Dr. said that one leg was actually Grade 1 and the other was Grade 2 - So go figure
Please do not let them talk of or do amputation. I think that's crazy
Please see a Ortho Specialist in this matter, b/c things are being said by this Vet that are uncalled for.
